Making proposals easier to find / organize / work on

It's a neat idea to figure out what people would really like to do. But I can already tell you what the results will be. You can either have proposals with divided support, but lots of attention. Or you can have proposals with full support, but limited attention. We already know how most proposals die on the other projects.

We don't need a better interface for making proposals. What's going to make it possible for any of these proposals to actually be tried and implemented?
