well, I think it can be a privacy issue.. especially if you use your real name and information about you, and photos...
imagine 5 years from now you want to get a job in a law firm and someone googles you... hmmm?
(or you land a new client and someone in the office has seen you on a site that is a bit, uhm...?)
Then again, if you work in a non-profit promoting understanding of social anxiety and other troubles, it may be okay?
