This writing competition has its fans and positive results as mostly I think it claims to make many people which keep on dreaming of writing a book to get out of the closet and start writing. And find out in the process if writing something like this fits them. It is about writing more at first, and writing better later, helped by peer pressure and some “gamification” maybe, all along a crazy schedule.
I agree with you that many of us would do better to find a healthier way to establish good writing habits, in a way that works for our own schedule. And maybe use a gentler method of accountability :)
