OK, I'm late to the game on it, but I'm really digging jQuery. I used to really dread having to do much of anything in javascript because of all the retarded cross-browser issues, the difficulty testing, etc. But jQuery is really turning that around for me - you can get some really neat stuff without having to deal with all the usual javascript stupidity (well, most of it) - check it out !
