Reaction to these two giants on the web sharing/making obvious they know things about us is causing an uproar in some circles. Yet many of us offer up what is, if you stop and think about it, a staggering amount of information.

Tara Hunt recently surveyed why (and what) people share; turns out many things are available online (home addresses, travel plans) and most who posted private stuff online (tweets from a date, photos of kids, feelings) didn’t delete it afterward — though some thought about it.

Just because something is publicly accessible doesn’t mean people want to be publicized.
