Because I keep seeing the "warnings" about phone contacts on FB, I've done a bit of reading and looking around. I'd like to say, and pay attention here, that the only phone numbers that I can see on that "Account->Edit Friends->Contacts" list are those of you who have also posted your numbers (to be exact, neither my mother's nor my mother-in-law's numbers are available on this page).
Now, this isn't to say that some of you _might_ be able to see contact information for some of your friends/family members who are not on FB--who am I to disagree with what you've seen with your own eyes?! To the contrary...I totally believe you, but I think, generally, this is your own doing: perhaps you have a "smart phone" with which you check FB, and your settings need to be adjusted (this is a natural progression given how fast the technology is "improving"); perhaps it _is_ in the privacy settings on your FB account (to be honest, even I do not read every little clause on FB); perhaps it's some other issue that hasn't yet arisen.
What I'm not convinced of is that this is some conspiracy by FB to access your contacts---I mean, what are they going to do, call my momma?! What I really think is happening is quite simple: I think there's a FB "scare" going around that has us (the general public) looking for a reason to switch to Goggle+. Ok, that might be a bit extreme, yes, but I don't think there's any reason at all to get all in an uproar about this phone book issue. Just fix it if it bothers you...
Oh, and here's some reading for you (ya know, the good scholarly--read:internet--kind):
