1. many users (big and small) are retiring.
2. an unbelievably large amount of drama.
3. the anything thread, (and many other forum games), being moved to the discussions
4. the death of discussions (caused by drama, trolls, spam and off-topic posts)
5. large bouts of inactivity.
6. and some other small things personally.
(Note: i am not retiring, in case you thought that)
