I tend to dip my toes lightly in the social networking (though, man, that badge stuff really works on the gamer part of my brain. I was pretty hooked on Four Square for a while, just for the stoopid badges) but here's one that looks promising to me and my interests: Untappd, the social network for drinking beer. The "if you're drinking this you might like these" recommendations are pretty intriguing (and, dangerous). I'm "fuzzy" on there, if you are too.
