Twitter has become my main source of new information, with Bloglines and email not far behind. I joined Twitter just to lurk and soon found hundreds of other users with similar interests, both professional and personal. One can manage the Twitter stream with Twitter lists (links to Twitter users sharing common information and support.)
What is a social network? Wikipedia discusses this with emphasis on physical and biological relationships such as family and kinship. Here, I consider the context of our online research environment and cyberinfrastructure such that, Social media are web tools that facilitate information exchange and social interactions.

Is our conversation limited to 140 characters? While announcing the 140 character science paper competition, Richard Grant looks sceptically at social media's (such as Twitter's) use for disseminating scientific results.

This is a huge topic about how to facilitate interactions between people, using these tools, businesses talking with their customers, sharing info rather than hoardnig it.

Gordhamer suggests some good guidelines, such as brevity, not putting too much investment into getting an immediate response and using your counterpart's preferred communication channel. He emphasizes connecting with others for a shared, mutual interest. Tamsen also shares some tips for successful social media participation.
Richard Simon posted The Complete History (spanning some 30 yrs) of Social Networking on his blog.
Clay Shirky's Here Comes Everybody and Matthew Fraser's Throwing Sheep in the Boardroom are both good starting points on social media and consequences.
I don't mean to be a knol-it-all. ;) Garrett
