browsed to bitbucket.org and ended up on some other dude's profile page
I just opened http://bitbucket.org/ in Safari and it showed me dhellmann's profile page. The URL displayed in the location bar was "http://bitbucket.org/". I was not signed in, but I do wonder if my session was mixed up with someone else's? I have no idea who Doug Hellman is and don't believe I've ever visited his profile before.
This happened around 18:28 PDT from IP address 220.127.116.11.
