Social Networking is Like Fast Food

OP here - so the experience may not just be about actually being on websites. The kinds of social technologies I'd like to see probably serve as more of a supporting foundation for social interaction IRL than an experience that lives on the web.

Things like online dating, Meetup, foursquare, are all sort of in this vein, but not quite. It's the kind of technology that creates memorable dining experiences with your friends - something like that.
