She's back! Marcy Simon, Eric Schmidt's ex-girlfriend, has always aimed to be with the hot tech company of the moment. In the '90s, she was all over Microsoft (and, we hear, Bill Gates). Then it was Schmidt and Google. Now that Facebook is looking to hire a VP of PR, could she be angling for the job? We hear she was rebuffed when she tried to land Facebook's outside PR account — San Francisco-based Outcast got the gig instead. But Simon is still relentlessly trying to work her way into Facebook. She's signed up Peter Thiel's Founders Fund as a client, hoping to use Thiel's influence as a board member to get tighter with Mark Zuckerberg & Co. I don't know about this, Marcy. Isn't Zuckerberg a little young for you?
