NaNoWriMo too scary for ya? Maybe this is more your line:
NaBloPoMo is an alternative to November's NaNoWriMo, National Novel Writing Month, the program wherein you crank out a novel in thirty days.
Some of us lack the imagination, stamina, and self-destructive impulses required to write a novel that quickly, but, by Grabthar's Hammer, we can update our blogs every day for a month!
