Probably one of the better ideas I've ever heard of, that I would really love to do, but would take some real convincing to get me off my duff to do, is Nanowimo, or National Novel Writing Month.

Its way more than a month really (I heard about it a few years ago from a friend that was seriously considering jumping into it). It is a great examle of how the internet works to bring people together and... well, I'd let the Nanowrimo folks explain details themselves:

National Novel Writing Month is a fun, seat-of-your-pants approach to novel writing. Participants begin writing November 1. The goal is to write a 175-page (50,000-word) novel by midnight, November 30.

Valuing enthusiasm and perseverance over painstaking craft, NaNoWriMo is a novel-writing program for everyone who has thought fleetingly about writing a novel but has been scared away by the time and effort involved.

Because of the limited writing window, the ONLY thing that matters in NaNoWriMo is output. It's all about quantity, not quality. The kamikaze approach forces you to lower your expectations, take risks, and write on the fly.

Make no mistake: You will be writing a lot of crap. And that's a good thing. By forcing yourself to write so intensely, you are giving yourself permission to make mistakes. To forgo the endless tweaking and editing and just create. To build without tearing down.

As you spend November writing, you can draw comfort from the fact that, all around the world, other National Novel Writing Month participants are going through the same joys and sorrows of producing the Great Frantic Novel. Wrimos meet throughout the month to offer encouragement, commiseration, and -- when the thing is done -- the kind of raucous celebrations that tend to frighten animals and small children.
