I've noticed the use of "she" instead of "he" when referring to a non-specific, hypothetical person has become more frequent. It seemed to be the pronoun of choice in most of my computer science textbooks. I've grown to like it, even though I usually still use "he" out of habit.
Other than that...I'm probably too young to have noticed much beyond changes in slang. Nobody says fartknocker anymore, I guess. I'm totally fine with language changing, though. There is no perfect inviolable entity known as English. The basic point is communication, everything besides that is just getting artsy fartsy about it.
