I like people knowing where I am. I like it because they know what time zone I'm in to know I'm awake or asleep. I like the fact that my friends know where they would need to be to look me up. I don't like people who just try to be friends with whoever they can find in the same city.

Seriously, I don't know you. I've never heard of you. You happen to live in the same general vicinity as me, that's all. So do a half-million other people. The only thing that sets you apart from them is that you also happen to be a member of the same site as me. Big deal. Please don't add me as a friend.
