Limit number of output lines generated at once (it was getting just a bit too spammy)
Handle "what do you think/how do you feel/etc. ... about me?" input
Try to make responses more likely to be coherent
Improve serialization/scheduling of pending output messages (sometimes lines were getting intertwined out of order)
Eliminate my own PMs from logfile to make it easier to find more interesting stuff
Allow a few more safe bot commands to be triggered
