One of my biggest complaints with websites is radical changes. I can see changing one or two things at a time, but drastic changes give me anxiety. NBA.com used to be really simple to navigate, but there are too many bored web designers involved there where all of the sudden, nobody knows how to look up a certain stat anymore. Ok, somebody does I'm sure, but it was something that didn't need changed, and only WAS changed so that some web designer had something to do. I hate changes that only happen because somebody needed to keep busy or justify their job and time.
