A List Apart is one of those sites that just impresses me with their content. I'm not a UI guy, and from time to time have to remember how to do something I had done somewhere else usually something to do with CSS. There's a specific example on Taming Lists from them that I refer to any time I'm trying to do inline lists that makes them play/feel nice other than display:inline.

If I'm ever searching for a CSS something and receive A List Apart link, it gets clicked
