> So I'm curious... is there any kind of "open-source incubator" out there? Like, a site with 500 developers signed up, they all vote on new project ideas, start a new project each month, kind of like a great big collaborative hackathon, in order to put out some really impressive piece of software, that then hopefully lives on?

There was something posted on here a while back called AssemblyMade. They basically do crowd-sourced development. To my knowledge, ideas are voted on, and then people essentially work in a democratic environment iterating on the development. In the end, the idea is that any profits made from the project will be split.
