Most people may not know, but Google Reader tracks every single entry you have ever read and there is no way to clear that list even if you remove all your subscriptions. Check out this link:

For me, this page shows some very old entries from the subscriptions I removed a very long time ago and there is now way to wipe it out! For this reason I wouldn't use Google Reader. (FYI, I use Cheetah News, which is a far better reader anyway, at least for me.)
