Just like the Netflix Prize, knowing which topics an entity is interested in, and having access to text they have written, is, in many cases, enough information to reveal who that person is, where they live, etc. You just plug the data into Google and correlate away.

Hi Brian,
I'm still not entirely clear on your complaint. Are you talking about Wikimedia (not random users, nor Wikipedia Administrators) having access to IP addresses from system logs? Or something else? What does "The IP address is helpful, but not necessary" mean?
Cheers, David...
