I, too, want a degree of anonymity when online. I don't post my last name, or my address, but there are plenty out there who do which scares me for them. I don't feel like anyone knowing that I live in NC is dangerous to me. Personally, I'm more concerned when I'm standing in a checkout line and the clerk asks me for my phone number to key into the register so I get "points" for my purchase in a store rewards program! Or handing a check over to a stranger for a purchase thereby handing them my name, address, phone number and other identifying information. Or buying online with a credit card. I've met a lot of wonderful people online that I consider dear friends. My life would not be the same without them.
