A while back when I tried to sign up for a Facebook account it was almost indistinguishable from a phishing attack -- it kept urging me to give them my email and other passwords to "help" me keep in better contact with my friends. (I ended up giving up, but apparently not completely enough to prevent an endless stream of "friend" requests from showing up in my mailbox.)
Signing up for Google+ this week was different. It already knew who all my contacts were, no passwords required.
I'm not sure, in retrospect, which was more disconcerting. If FB signup raised my phishing defenses, joining G+ felt more like a cyber-Mafia shakedown. All that was missing from the exhaustive list of friends and loved ones was "... it would be a shame if something happened to these people."
I'd say to look for me there, but it seems you won't have to.
