The NaNo website and its sense of humor seemed, in my humble opinion, set up that way simply to encourage people who might normally feel intimidated by the idea of writing a book, to just sit down and try it. Being forced to sit down and "put out" is, for some people, a major accomplishment in itself. And then actually finishing it? Major satisfaction.
My day job has let me meet a number of people who repeatedly say - "oh, I wish I could do such-and-such, but life gets in the way." I'd be willing to bet that life gets in the way for nearly all of us here, in whatever we do.
Some don't have quite the self-confidence to actually believe they might finish a big project, and accomplishing that might give them the self confidence they need to do something in another area in life.
I thought the site was fun and good-hearted, and a sense of humor will win me over every time. Just my opinion.
