For bugs 4415, 3850, and 1782: thank you, DW. Especially for 4415, which I thought was something on my end (with my s2, maybe) - had no idea it was beta-bug related. And anything like 1782 (improving comment nesting, which is the one of the few CSS/s2 issues that has consistently driven me insane, going back to 2005 or so on LJ) is equally awesome.
