Meh, I liked alignments. And I actually used them today... when playing out an NPC. Basically, when the PCs were considering the possibility of allowing a species to die out (essentially, genocide - they were just looking at all angles) I sat back and thought "how would a True Neutral Druid Handle This?" and eveything fell into place.
For the players, they can be sort of annoying, but on the other extreme, they do prevent guys from basically adopting the best personality for every situation - the ol "I'm Lawful Good in the city, Chaotic Evil in the dungeon" situation that seems to crop up from time to time.
