I was reading Neil Gaiman's blog and he posted a link to this site:
I have to admit, I'm serious considering doing this. Of course, I'm seriously considering doing this now, in May. When November comes around, I'll probably be seriously considering what flavor birthday cake I want (I"m thinking chocolate with cream cheese icing - yum!). But the nice thing about this is that a) you only have a month to do it, so you are not spending years and years writing a book that will never see the light of day and b) the expectation is that you'll write crap. I don't know why, but I often-times take myself too seriously. I can't stand the idea of somebody mocking me, which is why I get aggravated sometimes when I do a job and it's just not the best (a.k.a. any graphics work that I've done, baring a few that were due more to dumb luck than pure talent). But in this case, it's not only OK to fail, it's encouraged. Hopefully I'll remember this post in November and join up.
