A couple of years ago when FB first started causing privacy concerns, I sketched out a model for a freemium social networking site with user privacy as the top selling point. After deciding it was too early for the target market to consist of anything but Slashdot posters, I forgot about it. Is it time to think about it again, or is it just Slashdot and HN posters this time?
