Reader participation!!

I discovered that I have a whole mess of sock yarn (and a pound that is still undyed!) and only a couple of sock patterns that are on my must-knit list.

So I look to you, dear readers... what are your absolute favorite sock patterns on the web? I'm learning to do toe-up, so it doesn't matter whether they are toe up or cuff down patterns.

(And yes, I've looked through knittingpatterncentral, but I didn't want to just print things off willy-nilly... it's more fun to get recommendations!).
