Well, we can opt into it? Doesn't have to be forced....
Based on the replies I have seen, I don't think you guys are reading the idea right, I guess I assume you guys know that exposing personal information directly is a-given no-no and thus needs no re-iteration...
My apologies.
It would only show like a nickname and fav ride, not specific details... Like I said, HTC would do the matchmaking/linking.
