I know I've said this before, and even meant it, but the commenting is for real almost done. Not that I really think that people are clamoring to comment -- I mean, how would they, in the absence of a feedback mechanism -- but it's just one of those things that are done. People expect it.
I've still got to implement formatting (markdown, naturally) and name display. Apart from that, we're pretty much ready to ship. (Deal with stuff like spam filters if it becomes necessary. Do you expect it to become necessary? I don't.)
It's also written in the most direct cowboy coding style I could imagine, because most of this is a respite from the day job.
