I also just tried to log in about 6-7 times in a row (clicking the "login" link on the front page, reloading the front page in between attempts), and I repeatedly received the "expired link" page.
It also reliably happens clicking the "next page" link on the bottom of the front page; by the time I'm done reading the front page the next page link usually expires.

Please fix?
