Hey Facebook, That's Really Creepy!
A couple days ago, I was on Facebook and the feature where it suggests "People You Might Know" had the picture of a guy who lives on my block. We don't share any mutual Facebook friends. I only have one Facebook friend who lives in the neighborhood, and she doesn't have any other Facebook friends who live in the neighborhood. The guy whose picture they put up and I have nothing significant in common except the block on which we both live. So, despite my not giving Facebook my address, or phone number, it seems to know where I live.
I just had one thought about it, though, that may explain things. I'm pretty sure I've seen a Facebook feature that one allows Facebook to offer friend suggestions based on one's email address book - since the neighbor and I have exchanged email, it's possible that he used that feature and thus Facebook thinks I might know him and want to friend him based on that.
But upon further reflection, I think that the email address that my neighbor uses for me is not the same as the email address that I use with Facebook. So either Facebook knows where I live, or it has associated my email addresses. I'm not sure which of these I would like less.
