Cool thread! I recently started a sex (well mostly non nude) blog to test the waters. So far SE traffic has been surprisingly good. It doesnt hurt that many in the blogging world are very link friendly, and many blogs carry an unusually high pagerank for their relatively low traffic stats (if Alexa is to be trusted..). Link up if you'd like, my blog is only a week old but doing great:
