“ Since we can’t meet face-to-face, we may well just meet up online.”
To share experience
“ I have some great pictures from Tibet for you to see.”
“ Who is that cute girl I saw in the gym?”
Find contacts and make deals
“ Maybe Bob can introduce me to that VC”
Let your voice be heard
“ My friends don’t’ listen to me. Maybe others will.”
Do you have other reasons to join a social network?
Looking back into the past The idea of creating profiles and communicate with strangers are nothing new. Remember ICQ, IRC and MUD. What do you think have caused the sudden explosion of Social Network sites? Source: Social Network Sites: Definition, History, and Scholarship , D. Boyd and N. B. Ellison http://jcmc.indiana.edu/vol13/issue1/boyd.ellison.html
Example: Betweenness (1) Heather has less direct connection than Diane. (2) Heather has a “sweeter” spot in the network because she connects two groups of people. (3) Heather is a “single point of failure”. Source: http://www.orgnet.com/sna.html
Got it! Contact, school, favorites… HTML detected. But, what’s in the page? In order to help computer programs to better understand our profiles and social relationships, we need to express information in an explicit representation.
The idea only works if everyone support OpenSocial API. Facebook doesn’t support it, but it has a large user base.
Why new companies want to open up its information to other side?
OpenSocial API was incomplete and problematic when it was first released.
As reported by TechCrunch on November 5, 2007, OpenSocial was also quickly cracked. The total time to crack the OpenSocial-based iLike on Ning was just 20 minutes, according to TechCrunch, with the attacker being able add and remove songs on a user's playlist, and to look into information on their friends. http://en.wikipedia.org/wiki/OpenSocial#Criticism
