The pages seem scrambled for me. The portion at the bottom of the page where you can reply to thread appears somewhere in the middle overlapping a post. I can't actually see the section where I would enter my reply. I can reply to an individual post at least the ones that aren't overlapped by the bottom of the page. This started this morning.
I don’t think it’s a browser issue. I’ve seen it in both Safari 5.0.5 and the latest Chrome dev build, both on OS X.
Yup, same problem here. A lot of threads are stopping at the last post and I can't get to quick reply. Last time this happened it seemed to have something to do with the sponsored ads at the bottom of the page preventing the rest of the page from loading. Seems like this might be the case here too since that's exactly where the page stops loading and it seems to be random as to whether the full page loads or not.
