BTW, am also experimenting a bit with featured-commments formats and options whose results may show up on whatever threads or Commentariat pages affected.
Unless on a deadline, when putting something like this together, I think it's better practice to let it settle a bit, get backfed on it, see if any suppressed ideas or major glitches reveal themselves. Thought I was done middle of last week, for instance, then happened to notice I'd screwed up a bunch of the links while prettying up the code.
Also have to consider how to go about installing it, both as a technical-practical matter and as a matter of presentation and instruction, if any. I COULD just do it, and wait for people to notice or not. As far as I know, for instance, you and I and maybe VB are the only ones who have ever clicked on the preliminary State of the Discussion page at OT.
