When I redesigned this site, I got so fed up after fourteen days of wrangling with XHTML, CSS, and WordPress that I just kept the comments design from my old MT site – it was grayscale, it didn’t clash, it did. But it wasn’t quite what I intended. I’ve now updated how comments are listed, so you might need to refresh your stylesheet if individual pages look weird. And yes, I coded it by hand myself; it may look like other products on the market, but I stole not a sausage. Besides, I’m thinking of redesigning the whole shebang anyhow.
Update: well, it doesn’t quite look right in IE6 (negative margin not handled properly) but it looks functional, so I’ll leave it at that for now. Remember to refresh that stylesheet!
