It's one thing to provide our real name, address & phone number to web site's private databases, like Amazon. Even if that information ends up being in the open, it's not pleasant but it's a matter of public record (white pages stuff). But it's another making public all your comments, opinions, favorite things, latest liked articles, friends, family, current location and photos to casual surfers (or friends of friends) and associate them with your real name. That's why I don't use Facebook. That's why I don't use Google +. That's why I don't mind using Twitter. What you post on the web echoes in eternity... imagine all the stupid stuff you said when you were 16 being still a matter of public search when you're 46. Nope.
