It is kind of odd. I wonder how they found me. I usually don't accept adds from people like that. I always check out a person's profile a bit before I do anything with the friend request. I'd like to see that we have at least a couple things in common and that their questions and answers don't make them seem like creepers. If the account is private, I might add them, look around, then delete them quickly if I don't like what I see. I only have a few friends on here, so I don't know if my opinion really adds much to this.
