Seth Godin´s Daily Post

The artist says, "that sounds like business, and I want nothing to do with it. It will corrupt me and make me think small."
The businessperson says, "art is frightening, unpredictable and won't pay."
Because the artist fears business, she hesitates to think as big as she could, to imagine the impact she might be able to make, to envision the leverage that's available to her.
And because the businessperson fears art, she holds back, looks for a map, follows the existing path and works hard to fit in, never understanding just how vivid her new ideas might be and how powerful her art could make her.
There's often a route, a way to combine the original, human and connected work you want to do with a market-based solution that will enable it to scale. Once you see it, it's easier to call your bluff and make what you're capable of.

Rethinking Information Diversity in Networks - by Eytan Bakshy

How do your friends shape the information you see and read online? Social networking technologies like Facebook let us connect to hundreds, even thousands of people -- and have fundamentally changed how people get their information.

While much of our time is spent communicating with close friends about events in our personal lives [1], we also use online networks to share breaking news, discuss political issues and learn about new trends.  In 2010, my colleagues Itamar Rosenn, Cameron Marlow, Lada Adamic and I conducted a study on Facebook to understand the nature of information spread in social networks.

Some claim that social networks act like echo chambers in which people only consume and share information from likeminded close friends, stifling the spread of diverse information. Our study paints a different picture of the world.

Instead, we found that even though people are more likely to consume and share information that comes from close contacts that they interact with frequently (like discussing a photo from last night’s party), the vast majority of information comes from contacts that they interact with infrequently.  These distant contacts are also more likely to share novel information, demonstrating that social networks can act as a powerful medium for sharing new ideas, highlighting new products and discussing current events.

The research suggests that Facebook isn’t the echo chamber that some might expect – online social networks may actually increase the spread of novel information and diverse viewpoints.

Social Networks as Information Pathways
Economic sociologist Mark Granovetter was one of the first to popularize the use of social networks in understanding the spread of information.  In his seminal 1973 paper, The Strength of Weak Ties [2], Granovetter found that surprisingly, people are more likely to acquire jobs that they learned about through individuals they interact with infrequently rather than their close personal contacts. 

To explain this phenomenon Granovetter used social graphs to illustrate how networks relate to information access (Figure 1). When a person interacts with two individuals frequently, those individuals are also likely to interact with one another.  It follows that people tend to form dense clusters of strong ties who are all connected.

Figure 1: We are connected to core groups of strong ties that we interact with frequently and weak ties that we interact with infrequently. Granovetter's hypothesis about the "strength of weak ties" states that weak ties facilitate information flow from disparate clusters of people.

What do these structures have to do with information access? Since people in these clusters all know each other, any information that is available to one individual spreads quickly to others within the cluster. These tight-knit social circles tend to be small relative to people's entire social network, and when it comes to information about future job opportunities, it can be hard to find new leads.

Granovetter used the relationship between interaction frequency and social structure to explain why information about jobs is instead found through weak ties that we interact with infrequently.  Weak ties help spread novel information by bridging the gap between clusters of strong tie contacts.  The strength of weak ties informs much of the popular understanding of information spread in social networks.

Birds of a Feather Surf Together
But what about information that is more widely available, like news on the Internet? To understand the flow of more general types of information in society, it’s important not only to take into account how people are connected, but also the commonalities that promote the spread of information.  One of the most robust findings in social networks is that of homophily [3], the tendency of individuals with similar characteristics to associate with one another.  Individuals are connected to each other through workplaces, professions, schools, clubs, hobbies, political beliefs and other affiliations.  The homophily principle holds true for any kind of social network you can think of: close friends, professional contacts, classmates and even the people you ride the bus with. 

Today, these commonalities not only shape how often people interact and what they talk about, but also what kinds of information they as individuals seek on the Web.  Homophily suggests that people who interact frequently are similar and may consume more of the same information.  Individuals that interact less often tend to be dissimilar and may consume more diverse information.  This view of the world is illustrated in Figure 2 below.

Figure 2: Information spread in online social networks. Our study suggests that strong ties are similar and more likely to be tuned into the same web sites. Weak ties, being more dissimilar, tend to visit different websites.

Interest and Novelty
To understand how online social networks affect the spread of information, we used random variation in the News Feed to determine how likely a person is to share Web content if she did or did not see the content shared by her friends.  We found that people are more likely to share the information they were exposed to by their strong ties than by their weak ties on Facebook (Figure 3).   

Figure 3: People are more likely to share information (links to Web pages) that they were exposed to by strong ties in their News Feed [4]. Tie strength between two individuals is measured by the number of comments a person received from their friend on Facebook. Other measurements of tie strength, like the number of messages, co-appearances in photos, and discussion on posts are discussed in our paper [5].

There are many possible explanations for the increased flow of information across strong ties. One reason is that close contacts are more likely to be similar to one another, and therefore find content shared by their close friends more interesting.  An alternative explanation is that strong ties are more "influential", so that people are more likely to be persuaded to share information from their close contacts. 

We also investigate how Facebook amplifies information distribution. That is, if a friend shares something on Facebook, how many times more likely are you to share that information as a result of seeing it in the News Feed? The figure below shows how this multiplicative effect depends on the strength of your tie with that friend.

Figure 4: Weak ties spread novel information that people are unlikely to otherwise see. The figure above shows how many times more likely people are to share a page because of exposure via the News Feed from strong and weak ties.

We found that information shared by a person's weak ties is unlikely to be shared at a later point in time independently of those friends. Therefore, seeing content from a weak tie leads to a nearly tenfold increase in the likelihood that a person will share a link. In contrast, seeing information shared by a strong tie in News Feed makes people just six times as likely to share. In short, weak ties have the greatest potential to expose their friends to information that they would not have otherwise discovered.

The Collective Influence of Weak Ties
Ultimately, we are interested in how these network effects shape information spread as a whole.  Even though a person is more likely to share a single piece of information from one of their close contacts, it turns out that weak ties are collectively responsible for the majority of information spread. 

Let's consider a hypothetical example (illustrated in Figure 5). Let's say a person has 100 contacts that are weak tie friends, and 10 that are strong tie friends.  Suppose the chance that you'll share something is very high for strong tie friends, say 50%, but the weak tie friends tend to share less interesting stuff, so the likelihood of sharing is only 15%. Therefore the amount of information spread due to weak and strong ties would be 100*0.15 = 15, and 10*0.50 = 5 respectively, so in total, people would end up sharing more from their weak tie friends.

Figure 5: People are more likely to share information from their strong ties, but because of their abundance, weak ties are primarily responsible for the majority of information spread on Facebook. The figure above illustrates how a majority of influence (orange) can be generated by weak ties, even if strong ties are individually more influential.

It turns out that the mathematics of information spread on Facebook is quite similar to our hypothetical example: the majority of people’s contacts are weak tie friends, and if we carry out this same computation using the empirical distribution of tie strengths and their corresponding probabilities, we find that weak ties generate the majority of information spread.

The information we consume and share on Facebook is actually much more diverse in nature than conventional wisdom might suggest.  We are exposed to and spread more information from our distant contacts than our close friends.  Since these distant contacts tend to be different from us, the bulk of information we consume and share comes from people with different perspectives. This may provide some comfort to those who worry that social networks are simply an echo chamber where people are only exposed to those who share the same opinions.  Our work is among the first to rigorously quantify influence at a mass scale, and shows that online social networks can serve as an important medium for sharing new perspectives, products and world events.

[1] Common experience would suggest that we spend most of our time communicating with only a few individuals on Facebook.  To a large extent, this is true, and documented in Backstrom, et al. Center of Attention: How Facebook Users allocate Attention. ICWSM, 2011.

[4] It is important to note that very often, information does not "cascade" very far along the network.  This phenomenon has been observed in earlier research on Twitter in Everyone's an Influencer: Quantifying Influence on Twitter and has been studied across other networks more extensively in upcoming work by Sharad Goel and Duncan Watts at Yahoo! Research, NY.

Cautious Optimism at Chinese Art Auctions - by Nicholas Forrest

Although the latest round of auctions of Chinese artsuggest that the rate of growth of the Chinese art market appears to have slowed somewhat, the results are far from disappointing.  In fact, the sheer volume of works being sold combined with the prices being paid for many of the most desirable works appearing at auction in China is difficult to fathom.  While most of what we know about the market for Chinese art comes from Western sources, the true state of the Chinese art market can really only be determined by looking beyond the results of Western auction houses such as Christie’s and Sotheby’s, to the results of Chinese auction houses such as China Guardian auctions and Beijing Poly International auctions.
When delving into the depths of the epic auctions held by China Guardian and Beijing Poly International it becomes apparent that the Chinese art market is very much still dominated by works produced using traditional techniques and displaying a classical aesthetic.  Traditional style ink on paper paintings clearly influenced by Chinese calligraphy occupy so many of the top prices paid atauction in China that one could be forgiven for thinking that Chinese buyers aren’t buying anything else.  Although the 2011 Autumn auctions held by China Guardian and Beijing Poly yielded some truly remarkable results that seem to create a positive picture of the Chinese art market, the market’s reliance on such a narrow niche is cause for concern.
The highlight of the 2011 Chinese Autumn auction season was the sale of Xu Beihong’s ‘Cultivation on the Peaceful Land’ which was sold by Beijing Poly International for a record RMB 266,800,000(42,108,586.09 USD).  Coming in a close second was Fu Baoshi’s masterpiece ‘Chairman Mao’s poetry octavo volumes’ as sold by Beijing Hanhai auctions for an artist auction record of  RMB 200,000,000 million (31,565,656.74 USD). Shengjia auction sold “Chairman Mao’s poetry octavo volumes” in 2003 for 19,800,000 – a record at the time for Baoshi’s work.   The third highest price went to an album of landscape paintings by the master Qi Baishi which fetched RMB 194,000,000 (30,618,687.03 USD) at China Guardian’s “Grand View: Chinese Paintings Highlight” held on the 13th of November.  Previously sold by China Guardian for RMB 5.17 million in 1994, Baishi’s landscape album is an good example of how rapidly the market for Chinese art has developed. Also breaking the RMB 100 million mark was Wang Hui’s “Chinese poetic figure” which was also sold by China Guardian for RMB 126,500,000 (19,965,277.89 USD).
One of the most notable diversions from the traditional ink on paper paintings was the sale of San Yu’s CHRYSANTHEMUM oil on board for RMB 34,500,000 ( 5,445,075.78 USD).  The Chinese born, Paris trained artist’s CHRYSANTHEMUM resembles the work of European abstractionists more than the work of any traditional Chinese artist, but still exhibits elements reminiscent of the traditional Chinese aesthetic.  The auction record for a work by Yu is USD 14,726,564.

The erosion in the paid media pyramid - Seth Godin -Learn how to sell

Starting from the bottom:
Free content is delivered to anyone who is willing to consume it, usually as a way of engaging attention and leading to sales of content down the road. This is the movie trailer, the guest on Oprah, the free chapter, the tweets highlighting big ideas.
Mass content is the inevitable result of a medium where the cost of making copies is inexpensive. So you get books for $20, movie tickets for $8 and newspapers for pocket change. Mass content has been the engine of popular culture for a century.
Limited content is something rare, and thus more expensive. It's the ticket that everyone can't possibly buy. This is a seat in a Broadway theater, attendance at a small seminar or a signed lithograph.
And finally, there's bespoke content. This is the truly expensive, truly limited performance. A unique painting, or hiring a singer to appear at an event.
Three things just happened:
A. Almost anyone can now publish almost anything. You can publish a book with out a publisher, record a song without a label, host a seminar without a seminar company, sell your art without a gallery. This leads to an explosion of choice. (Or from the point of view of the media producer, an explosion of clutter and competition).
B. Because of A, attention is worth more than ever before. The single gating factor for almost all success in media is, "do people know enough about it to choose to buy something?"
C. The marginal cost of one more copy in the digital world is precisely zero. One more viewer on YouTube, one more listener to your MP3, one more blog reader--they cost the producer nothing to produce or deliver.
As a result of these three factors, there's a huge sucking sound, and that's the erosion of mass as part of the media model. Fewer people buying movie tickets and hardcover books, more people engaging in free media.
Overlooked in all the handwringing is a rise in the willingness of some consumers (true fans) to move up the pyramid and engage in limited works. Is this enough to replace the money that's not being spent on mass? Of course not. But no one said it was fair.
By head count, just about everyone who works in the media industry is in the business of formalizing, reproducing, distributing, marketing and selling copies of the original creative work to the masses. The creators aren't going to go away--they have no choice but to create. The infrastructure around monetizing work that used to have a marginal cost but no longer does is in for a radical shift, though.
Media projects of the future will be cheaper to build, faster to market, less staffed with expensive marketers and more focused on creating free media that earns enough attention to pay for itself with limited patronage.

ART DUBAI´s Art Week Education Programme

Art Dubai is delighted to announce the launch of the Art Week Education Programme, providing opportunities for young people in the UAE to get involved in the world of contemporary art and design.
A new series of monthly seminars will begin at the Pavilion, Downtown Dubai, on December 4, 2011 as part of Art Dubai’s continual efforts to grow art audiences, support local talent, and provide educational opportunities for locally-based students and graduates.

Art Week (March 15-25, 2012) is an umbrella initiative that includes new gallery exhibitions and artists’ projects, fairs, performances and major museum shows, taking place across the UAE and the Gulf to coincide with Art Dubai.
The aim of the new seminars is to offer participants an opportunity to gain a broad understanding of contemporary art and design; meet like-minded students, graduates and enthusiasts; and the chance to apply for a place on the Art Week Internship Programme.

The seminars take the form of a series of talks and workshops by leaders within the field. Once a month, from December to March, attendees will have access to experts sharing their knowledge, insights and practical advice. The seminars will also be an opportunity to network with the speakers, like-minded students, graduates and individuals.
The seminars will cover a wide range of topics; from an introduction to Art Week and the internship programme; gallery management and exhibition-making; foundations and the not-for-profit sector; artists’ residencies; and the contemporary design industry. Talks will be given by industry key figures, gallery owners, educators, previous interns and artists.
The seminars are also targeted at potential interns and on-site fair assistants.

“I have interned with Art Dubai twice already. It’s a great experience to get exposed to the art world, gain valuable knowledge, meet people and make contacts for the future,” said Madiha Qadir Sheikh, from the College of Fine Arts, Sharjah.

“The office is a very active place where people are open to new ideas. I felt I was contributing as I was given a few responsibilities. It was fantastic to be part of the team and learn how a major international art fair is organised and managed.” Noor Al Khaja, American University of Sharjah.

“We are delighted to be growing Art Dubai’s educational programme to encompass year-round seminars and educational initiatives that will offer insight on the latest developments in the Middle East’s contemporary arts landscape. These programmes have been designed to offer students, graduates and arts enthusiasts a chance to actively participate in successful international fairs, immerse themselves in the local cultural community and engage with artists, gallerists, curators, filmmakers and other visionaries,” said Antonia Carver, Fair Director, Art Dubai
“Our foremost ambition is to create a platform where local participants can create and exchange ideas and play an interactive role as the region’s art sector develops.”

Art Dubai’s internship Programme was initiated in September 2007. Since then over 300 students and recent graduates from 40 nationalities and 18 educational institutions have participated in the scheme and gone on to find further work experience opportunities and permanent placements within Art Dubai and its partner organisations.

Meryl Streep Movie List

More and more I fall in love with Meryl Streeps work. Lately, I am watching lots of movie of her. If you dont know already, IMDB.com (Internet Movie Database) is a great source for you to search about actors, movies and put together a great Movie List for the weekend. I am having trouble sleeping lately, so I take my laptop to bed with me and watch a movie every other day.

I´ve done a Meryl Streep List and I have watched so far: 
1. The Devil wears Prada
2. Lions for Lambs
3. Mamma Mia!
4. Kramer vs Kramer
5. The Bridge of Madison County (I am still crying over this one!)
6. The hour
7. Its complicated!
8. Doubt
9. Prime

I have just finished watching The Bridge of Madison County and I am still crying over it. It was so simply, deep, thoughtful and delightful. This is one kind of movie you always want to watch but I end up not having the chance to. I have always had it in my To-Watch list and finally I did it. Meryl Streep plays an Italian woman called Francesca and Clint Eastwood plays Robert Kinkaid, a National Geographic´s landscape photographer. Meryl Streep is a house wife mother of two and Clint ends up knocking on her door asking for directions. They have a four day affair and iniciate a lifetime platonic romance. It is so dense and beautiful.

At the end, Robert sends her a book with a Lord Byron poem:
There is a pleasure in the pathless woods,
There is a rapture on the lonely shore,
There is society, where none intrudes,
By the deep sea, and music in its roar:
I love not man the less, but Nature more,
From these our interviews, in which I steal
From all I may be, or have been before,
To mingle with the Universe, and feel
What I can ne'er express, yet cannot all conceal.
- Lord Byron

Movie quotes:

Francesca: And in that moment, everything I knew to be true about myself up until then was gone. I was acting like another woman, yet I was more myself than ever before. 

Robert Kincaid: This kind of certainty comes but once in a lifetime. 

Robert Kincaid: I don't want to need you, 'cause I can't have you. 

Francesca: Robert, please. You don't understand, no-one does. When a woman makes the choice to marry, to have children; in one way her life begins but in another way it stops. You build a life of details. You become a mother, a wife and you stop and stay steady so that your children can move. And when they leave they take your life of details with them. And then you're expected move again only you don't remember what moves you because no-one has asked in so long. Not even yourself. You never in your life think that love like this can happen to you. 
Robert Kincaid: But now that you have it... 
Francesca: I want to keep it forever. I want to love you the way I do now the rest of my life. Don't you understand... we'll lose it if we leave. I can't make an entire life disappear to start a new one. All I can do is try to hold onto to both. Help me. Help me not lose loving you. 

Robert: When I think of why I make pictures, the reason that I can come up with just seems that I've been making my way here. It seems right now that all I've ever done in my life is making my way here to you. 
Francesca: So, do you want more eggs or should we just fuck on the linoleum one last time? 

Francesca: I realized love won't obey our expectations, it's mystery is pure and absolute. What Robert and I had, could not continue if we were together. What Richard and I shared would vanish if we were apart. But how I wanted to share this. How would our lives have changed if I had? Could anyone else have seen the beauty of it?

Robert Kincaid: Things change. They always do, it's one of the things of nature. Most people are afraid of change, but if you look at it as something you can always count on, then it can be a comfort.

The next Meryl STreep movie I want to watch is Sophie´s Choice, but I am kind of reluctant on this one. It seems really sad. I would need to be in the mood for it...I just dont know if I need to be in a bad-down mood and watch it to cry it all or to be in a good mood to look at it with other eyes....I never know the best mood to watch certain kind of movie......If it is a good mood for a down movie, a down mood for a down movie, a good mood for a fun and light movie or a down mood for a funny movie...There are lot of choices before watching a movie...aff !

lets see which day!!!
