I've done NaNoWriMo every year since 2003. I've actually hit 50,000 words about half the time (4 wins, 4 losses). I'm doing it again this year in the hopes of moving my average up to 5 wins over 4 losses -- even though that means it may interfere with pushing more chapters of The Points Between out the door. I know it's crazy. I do. I really do know it.
Anyway, I was toying with trying to do something ridiculous this year, like posting it on my site as I go -- sort of an extreme sports version of NaNoWriMo-driven webfiction -- but putting up 1667 words a day, every day... quality concerns, you know? NaNoWriMo isn't about editing, you do that after. Thre woul db etypo s. We'll see.
Anyway... any of you jumping in?
