How would the ongoing open section work? Drawing a distinction between a more serious section and a less serious one has the problem that eventually almost no one will post in the more serious one—Main/Discussion on LW, for example. (I had this problem when I had a blog: I’d set up a sideblog and then stop posting on the main blog. I went through about four cycles of that before I stopped entirely.) But I don’t think there was a problem of everything drifting from Discussion to open threads, nor do I think such a problem would have arisen—it felt like there was much more of a distinction between Discussion and open threads than there was between Main and Discussion.
