You'll probably notice that the comments are completely different. They suck way, way less now.
2. New comment notification
3. Moderation revamp
4. No more awful pale blue
On #3: once you get 100 points you will be able to moderate by choosing a positive or negative descriptor (or "Normal," for whatever reason). Positive will add a point to the comment, negative will take one away. Anything less than one--the default starting point--will be automatically collapsed. Click to embiggen. Logged-in users can set a lower or higher threshold for collapsing.
Userpoints are not hooked up to this new system, but that is next on the list. I think I'm going to have to sponsor development for that so it might not be immediate. I'm also going to make some small usability tweaks (less date, more headline, for one).
It works for IE (I even checked this time!) but there is a bizarre and unfortunate CSS bug that makes the author pane scarlet and grey. I'll work on that but, as always, STOP USING INTERNET EXPLORER. WHAT IS WRONG WITH YOU? Until I fix it just stare at that horrible color combination. Yeah.
UPDATE: I changed the setting so people participating in the thread can moderate it. Also I hacked out half of the admittedly-excessive options available in the dropdown.
