Kevin Kelleher has captured the conundrum Facebook finds itself in.  A Catch 22 situation. I and some others I know, have felt this way for some time. The slow motion flash mob, or high velocity Adizes corporate life cycle of Facebook is reaching an obvious tipping point.  I think people are tiring of the constant issues of abuse of privacy, and Kevin has also sensed the faddishness of it.  Employers now scour Facebook before hiring anyone, so why go there anymore?  Maybe another model will emerge to take Facebook’s place.
