Polishing it up would be nice, but might never get there. Sticking it all in a wiki (ETA: a la mooism) would be better than the current situation, as at least it would be available, and people could badger you on what they're interested in. But I know how it is: one always thinks "But tomorrow I might format it properly" :)

Mostly, I like dennyd's suggestion. Once a week (or month, or 6 months) write one up a bit and publish it. You should keep ahead of yourself that way.

Specifically, I'm curious about the sf novel ideas :) If you'll really never take up, you never know, they might inspire someone else.
