Honestly I don't know why this level is surprising.  I think as the world gets more connected, the community is gonna get a little smaller (in feel, at least), and we're going to become less anonymous.  If the bad guys get less anonymous too, and nobody pretends that this stuff is sufficient to definitely identify me, I don't see a problem.  Yup, big "ifs."
