Not ALL new posts appearing in Hotposts
One thing I've noticed is that the cache of Hot Posts is not static when you move from one screen to the next, i.e., clicking to the second 40 posts from the first 40. It seems to continue to refresh, which you'll notice if the 40th post from the bottom of the first page is now on the top of the second page. To make sure that I don't miss any, once I've scanned through all the Hot Post screens, I click on "Hot Posts" button once more and return to the first screen to catch any new additions before I hit "mark all as read". Otherwise some of the new postings that have come in since you started will be missed. This seems to be a bug to me that should be corrected.
