View New Content wasn't working for me this morning either. I used the Delete My Cookies link at the bottom of the page and it started working. I get many more than I should be getting (older) but new content is current.
Edit: Maybe someone knows if there is a cookie that can be deleted so that every cookie doesn't get trashed.
