I generally ignore self-appointed censors, but I was asked to take a look at this project. I guess I was supposed to be upset by this, but I thought it was seriously funny. Several times I laughed so hard I almost had an accident. The manifesto is particularly precious. They've even got their own weblog going. I'm pretty sure it's not a parody, either, which makes it even more hilarious.
As one of the few successful and actively published science fiction writers in the world, I suppose I should also express my view. So, okay, you want to know what science fiction should be? Anything you want it to be. There, let's make that my manifesto. And I didn't even go to Clarion. How about that.
Excuse me, I have to go laugh some more now.
