The single most annoying aspect in CSS (IMO) is class and id names, or better: keeping them predictable (we already used that one) and concise (that one should be named that). I'd like to know if there's a simple "namespace convention" that works. As features get added, I always end up making up class/id names or waste time hunting them down. Especially dynamically generated stuff.
