What was porn star Ron Jeremy, pictured above, doing at the Palace Hotel for the last night of Web 2.0 Summit? Or, more importantly, who was he doing? Somehow we doubt he was there for the panels, since his career as a tech blogger seems stillborn. He hasn't posted a new "Techsmart with Ron Jeremy" video on his Heavy.com channel since May. No wonder the porn pioneer had nothing better to do than play the John Doerr drinking game. All we know is that he did indulge us when we asked for a picture with some Web 2.0 Summit paraphernalia. Have any dirt on his presence? Please share.
