While you are flying Lufthansa, Lufthansa automatically sends status updates to your social networks (twitter, facebook, …) and show all the updates on a globe. It’s travel made social. Check MySkyStatus.com

Duncan Watts is principal research scientist at Yahoo! Research, where he directs the Human Social Dynamics group.

Although internet-based research still faces serious methodological and procedural obstacles, Duncan proposes that the ability to study truly ’social’ dynamics at individual-level resolution will have dramatic consequences for social science. To illustrate this, he will describe four examples of research that would have been extremely difficult, or even impossible, to perform just a decade ago:
* Using email exchange to track social networks evolving in time
* Using a web-based experiment to study the collective consequences of social influence on decision making
* Using a social networking site to study the difference between perceived and actual homogeneity of attitudes among friends
* Using Amazon’s Mechanical Turk to study the incentives underlying ‘crowd sourcing’

This great presentation tells you:
* how to use Netvizz, a Facebook application for exporting your Facebook social network or the network of a Facebook group in the form of a .gdf file
* and then how to import the .gdf file into gephi for analyzing and visualizing your network: you can select and parameter layout algorithms, change colors and sizes, etc.
Amazing!

According to stats published by Facebook, Facebook has currently 400,000,000 active users. This would make it the third most populous country in the world, after China and India.
Do you bet it will overtake India’s population (1,166,900,000)? In how many months?

From NYTimes A Facebook Christmas Love Story, it seems loneliness is contagiousness and spreads to your social ties on social networks (just as another study has found about spreading of happiness and spread of obesity and smoking behaviour).

An article in The Journal of Personality and Social Psychology presented the argument that feelings of sadness and isolation can spread from the folks who are feeling them not only to their friends but also to their friends’ friends.

Every research finding is so ephemeral nowadays. Maybe what we are doing is not science after all? Or maybe it was like this even years ago but simply it was slower, i.e. it took 20 years to get a new study confirming or not the previous one. Or better, every new study is just a small contribution in an ocean of possibilities and many of them will crystallize over time into “our comprehension of the Reality”…

From Facebooking Won’t Affect Your Grades, Study Finds. At Least Until Next Month’s Study Tells You It Will

It seems like every week there’s a new study about whether or not the sky is falling because of Facebook and other Web sites of its ilk. Now the University of New Hampshire offers new research that falls squarely in the sky-is-not-falling category, at least not when it comes to the impact of social media on students’ grades.
A survey of 1,127 University of New Hampshire students pursuing various majors found no link between how much time they spend Facebooking, tweeting, and YouTubing and how well they do in college.
The breakdown: 63 percent of heavy social-media users got high grades, compared with 65 percent of light users. The findings held up for academic slouches, too. Thirty-seven percent of heavy users got lower grades, compared with 35 percent of light users.
The university’s message: “Parents worried that their college students are spending too much time on Facebook and other social-networking sites and not enough time hitting the books can breathe a sigh of relief.”
Or not.
In April, a researcher at Ohio State University found that students who use Facebook reported earning lower grade-point averages than nonusers of the social-networking service. Then again, the researcher said in an interview with The Chronicle that she didn’t have enough data to determine whether Facebook use causes students to do poorly.
What research can prove is that when those students get married there’s a good chance Facebook might help cause their divorce. At least that’s the story until next month, when someone else is bound to tell us how Facebook is saving relationships.
Oh wait, someone already did.

Very clever use of Facebook by Ikea. Ikea created a profile for the director of a new store. He uploaded many photos of Ikea-furbished rooms. The first to tag her name over a product won it! Very clever!
Very cheap campaign (from Ikea point of view) and very viral!

Great paper by Mikolaj Jan Piskorski (Harvard Business School) “Networks as Covers: Evidence from business and social On-line Networks” . Amazing which patterns everybody can unveil when (almost) all out social interactions leave electronic trails everybody can collect and analyze! Amazing and of course scary!

This paper proposes that networks can act as covers which allow actors to participate in markets while maintaining a plausible excuse that they are not. Most generally, a cover is any action which allows ego to signal to alter that he is of type A when in reality they are of type B.

Evidence from another network (the paper does not explicit which one but says “the network has been designed largely for people to keep in touch with their friends, and not for business purposes. Results indicate that almost 70 per cent of all activity on this on-line network is related to viewing profiles and pictures of others.”, so I might guess the network is Facebook, wondering why Mikolaj didn’t write which is the network… ): Men in particular look at pictures of women they do not know. Furthermore, regression analysis shows that men who publicly declared themselves to be in a relationship are more likely to examine profiles and pictures of women they do not know. Consistent with the view of networks as covers, (…) men in relationships and with large on-line networks are more like to look at women they do not know. In contrast, single men with large networks are more likely to look at women they do know. Implications for network theories as they pertain to organizations are explored.

Aggressive and creative marketing campaign by Burger King.

What would you do for a free Whopper? Now is the time to put your fair-weather Web friendships to the test. Install Whopper Sacrifice on your Facebook profile, and we’ll reward you with a free flame-broiled Whopper when you sacrifice 10 of your friends.

InsideFacebook reports that in one week, the app was used by 82,000 people to delete over 230,000 friendships on Facebook. Then Facebook placed some restrictions on the application and Burger King decided to conclude their campaign. In fact, Burger King got what it wanted: attention! In few days!
Creative use of social networking marketing!!!
