I think every writer must have folder(s) full of WiPs; it seems to be part of the process. I think I need to get better at focussing and prioritising, though. It would be nice to get more pieces finished and posted!

Currently, I have a Scrivener project called The Plotbunny Farm and I put all my ideas in there, sorted according to a sort of Venn Diagram process: when is it due, how close is it to being finished, and how much is it nagging me to get written.

I think of it in farming terms, with folders for Fallow Fields (old ideas that I can't bring myself to throw away yet), Seeds (bare-bones concepts), Seedlings (detailed concepts, with a couple of scenes written), the Current Crop (things I'm actively working on, or that are close to being finished, or being beta'd), and Last Year's Harvest for my finished, posted works.
