TownKings is an interesting concept. (TownQueens is the sister site for women.) They both look like they’re geared toward dating, but they also attempt to connect you to local parties and information about your friends.
My only concern with sites like TownKings and FatDoor is privacy.
I’ve registered on the site to test it out. Feel free to send me a friend request. You can find me by my username, cstock. So far, I’m the only guy who’s joined in my area.
