That's what I thought. But yesterday (and before then too, but yesterday really got to me), the home page would tell me new posts in my watched forums, and I would open the forum to find the top several threads had no new content.
You might think I was simply hitting the back button instead of refreshing, but I always use the "home" button on my floating toolbar or the ATP logo on the top left center of screen to go home again, or I refresh. So ATP was apparently misbehaving yesterday, which is what led me to comment in this thread again.
