Have a second tab (or window for those working with internet software 5+ years old) open to the main screen with all the topics. After you hit "add your post" and nothing happens...go to the other tab, and refresh. Either your new topic, or the existing thread you just commented on, should now be at the top. This, rather than pound the "add your comment" button until something happens, and adds half a dozen posts.
Hopefully this cuts SOME of the clutter.
