What's this about the new feature on the geocaching site, "friend requests"? First I thought I had no "friends", then I got a request from someone who started caching yesterday and I was stuck for an answer. How do I know I want to be his "friend"? Maybe he's a really nice person. Maybe he's a mass murderer (but I doubt it). Anyway, I accepted but have no clue what that means, if anything. Somehow this feature sounds more like My Space or whatever teenagers are into.
