I have switched my LJ over to S2 because I read in the 2007 wrap-up thread
that you can expand collapsed comments using the Expressive series of layouts, and that's reason enough for me (I *detest* auto-collapsed comments). So yeah. Not real thrilling, but there it is (it was between this one - Minimalist Blue - Inked Blue, which had a blue feather, or Typekeys Rainbow, which had rainbow typewriter keys, but I went with something simple). I'll be fiddling with it over the next few weeks as I learn more about customizing, I'm sure.
So, as a test, I would like more than 50 replies to this thread so I can test said uncollapsability.
GO.Edited to add:
By God, it works! Not nearly as well as I'd hoped it would, but it's a start.
