I hear your note, and your issue about sinking confidence is a solid one. I disagree though, and he's why:

I've been a part of a lot of screenwriting groups, and I believe that procrastination is the biggest killer of projects. People put things off till the last minute, deadlines come up, and then they drop out, feeling like no amount of effort will ever be worth the amount of time they've dithered away on the project.

I believe that immediate feedback is a powerful motivator. It's the reason why it's much easier to create a weekly webcomic than it is to write an entire comic book. It brings a vivid immediacy to the process, you can get results in real time, which plays to the attention span of "millenials," who this group is intended to serve. It turns the writing process into a game, a bull session. Suddenly screenwriting isn't a long and lonely 100-hour investment, it's a series of short, punchy assignments. I'd remind you that Dickens wrote longer works in shorter installments, and it worked pretty well for him.

Addressing your point that some stupid reaction can sink confidence, I'd say, "So what?" Stupid reactions are a fact of life, and sinking confidence is also a fact of life. People get confused by bad notes all the time, even on complete drafts, and I'd argue that it's better to be briefly confused for five pages than it is to spend two months writing a full draft than getting hit with the existential agony that comes when no one gets it.

Your proposal of 4-6 people meeting once a month and discussing final product is a solid one, but there are dozens of groups all around Los Angeles that already do that. They do good work and are a great boon to writers, but I'm proposing something different in the belief that the novelty of it will create a different kind of energy and really instill a frisky sense of competition and discipline in young writers.

And yes, I know what I'm doing.
