Back in July I posted a blog piece that talked about the long tail effect on social marketing. In it I talked about Facebook being the “mass hit” rather than the long tail but pointed out that social networks are beginning to pop up catering to diverse communities as are communities within social networks like Facebook. It would appear that I am not the only one that believes this. Read Chris Anderson‘s own blog this week contesting that Facebook apps are not long tail either. He concludes this following detailed analysis conducted by Web 2.0 guru Tim O’Reilly.
