The previous poll asked: How frequently you use/visit these Social Network sites for Analytic / Data Mining Purposes?
The results show that LinkedIn (and its groups) is the most frequently visited site, followed by AnalyticBridge, and Facebook.
No voters have used MySpace and only 3 reported using Twitter professionally.

Comments
Frank wrote that Xing is missing, the dominant social networking plattform for professional contacts in Europe and number two world-wide after LinkedIn.
FaceBook and MySpace seem to be more for private use. This is at least what the design of the four platforms and the number and content of the groups on these plattforms suggest.
Worth mentioning in this context might also be Google and Yahoo groups.
