Peeps need to watch their privacy settings, is all they need to do. Too many people I see leave it being visible to "friends of friends" for way too many things. It's amazing how many actual friends of mine have over a 1,000 "friends," but to me, probably like 980 of them are total strangers.
I got phone numbers, email addresses, physical addresses, all always popping up into my home page from "friends of friends" status updates. I know for a fact these real friends barely (or even?) know all these supposed "friends" they accumulate, and a few of them are of the young, gorgeous persuasion, that should really be looking out for that kind of stuff, especially since they might be spreading that info to not only the strangers they call "friends," but to the completely total strangers those friends call friends if they comment on anything they do!!!
It's a useful tool, but you really gotta use it intelligently...
