I've noticed that if I'm paired with the right person and we write roleplaying-style (i.e. both writers adopt some of the characters as their own, and we write out their dialogue interactively in a chat), I can produce lots of good fiction fast. However, all of my attempts to produce longer works of fiction when writing on my own have failed, even though I have several short stories that I'm happy with.
If anybody would be free during evenings, European time, and would want to try writing something with me in that style, let me know.
Assuming I read the conversion table I looked up correctly, eight pm GMT is noon Pacific. The roleplay style you describe is how the first go-round of Elcenia was produced. I'll do some of this with you to see how it goes - no long term promises.
This community has a recurring interest in "rationalist fiction," and several members who are writers. I wonder if it would be useful to create a space where Less Wrong members could provide each other constructive criticism and encouragement on in-progress original writing projects?
Disclosure: I'm working on a sci-fi novel right now, and my regular circle of "beta readers" are fantasy fans and aren't providing much feedback on the new project. I am much, much more productive as a writer when I get steady feedback, so I have a personal interest in looking for something like this. Less Wrong came to mind as a community of intelligent, creative, forward-looking types who are likely to enjoy sci-fi.
