I have noticed in the past two weeks, that certain functionality on DevMaster is broken. For instance, when I click the 'New Posts' link, it almost always says that there are no new threads, even though I can go to the forums and see for myself, that there are infact new threads.
The 'Quick Links->Mark Forums Read' sometimes also just leaves things as they were.
EDIT: Actually, the 'New Posts' link says "Sorry - no matches. Please try some different terms."
