Pending Comments
I'm turning off pending comments for now, because I'm going to bed and I don't like the idea of something this new running without me being able to watch it.<p>One thing I noticed while it was turned on was that the comments were actually pretty good.  It may be that bad comments tend to be concentrated on particular threads, and that the right way to implement pending comments is per-thread rather than site-wide.  That was actually the original plan, but it was simpler to implement site-wide, and I usually try to do the simplest thing first, in case it works.
