Interesting test, So, there's not a lot that's private, is there.

Hmmm. I wonder how much is server side, and how much is user side? There are commends in the web browser to list your settings and pc info. But this is to display it to your self, nothing gets sent anywhere else.
Also, I see no private data there. It's just your screen resolution, browser and if you have cookies on (which is easy to get I guess). No actual info about me, or my pc.
