I'm having a conceptual problem with this whole "friending" thing. With no PM system and the inability to see e-mail addresses of people who are not friends (assuming the e-mail isn't hidden), I have no way to talk to people who send friending "invitations." And I think that's something of a problem.
Here's a situation that has happened more than once: I get an "invitation" from someone. I don't recognize the name and my (one) game is not even in their library. My assumption is that this is a user essentially "phishing for friends," which I have no interest in, but how do I know for sure? I'm concerned that maybe they found me by location and are interested in looking at my (one) game, but have no way to ask about it other than "friending." I can't ask them why they sent the invitation.
Am I reading too much into this or do other people see the inability of users to talk privately before "enlisting" as friends a problem?
