A few weeks ago I posted about the role of social networks in the B2B marketplace. This morning I attended a webinar, presented by Hitwise, which focused on the growing popularity of social networking sites. LeeAnn Prescott of Hitwise mentioned that in October 2006, social networking accounted for 1 in every 20 internet visits. 82% of these were from myspace.com. That does seem like a lot doesn't it? By the way did you know that a search in Google for 'myspace' returns about a half of a billion results?
