Definitely we need a "trickle up" system so that active topics don't get buried under three pages of other stuff in a day or two. It's impossible to continue a discussion longer than a couple of days no matter how interesting or important the subject. That's just not right. It leads to people having to restart threads to keep them near the front. Yes, I know about the option not to show read posts, but it isn't the default and I don't think many people use it.
