I've never tried NaNoWriMo and have never really been tempted. I'm a pretty slow writer, and certain I'll produce absolute dreck if I try this. For those of you who are doing it, what's your goal or motivation? For those of you who've done it in the past, was your goal met? Were there benefits or drawbacks you didn't foresee? Are you sold on it, or is it something you've done once and "never again"? Did/do you consider it mostly an exercise to get the flow going, or do you hope to, or did you, produce something you can revise for submission?
I've left you a few days to respond before the big event actually starts, in case you're all going to disappear from the blogosphere for a month. :) Hope it works great for any of you who are taking the plunge.
