Some people in the German support forum reporting a problem with their comment box. They can not comment on any blog. All three login possibilities are showing "You are commenting with WordPress/Twitter/Facebook" and the "Send"-Buton does not work.
Changing the browser doesn't help. Deleting Cache & Cookies does not help, too.
