Well, it's late. I got the comment rating system in place on kuro5hin.org tonight, finally, after having accidentally "upgraded" it to the half-completed version a couple days ago. Whoops. But the working system is in place now, and I'm really curious to see what the reaction is.
Now I just need to get some kind of "x new comments since your last visit" function in place, and I'll be ready to add to the docs and put together a decent 0.4 release. Fun fun. :-)
