I feel I've developed into a slightly more solid player. Well, 'solid' is probably misleading, I still throw stuff at my opponents as reckless as ever. But maybe a slight change there. Also my endgames seem to have become more solid. I defend lost positions better, especially in a time scramble. Which I guess is the essence of blitz in a way, making 'winning the won game' as hard as possible for the other guy. And on the flipside simplifying my own won games as quickly as possible.
That's about it really. See you next year at 1800.
