This seems cool, as far as I can tell it's more for one's personal education, rather than producing something for others to use?
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?
E.g., an open-source iTunes integrated with bittorrent, complete with iPhone app. A font-design program for amateurs. A keyframed animation tool that outputs to HTML5 canvas. A dynamic texture generator program. A user-friendly neural net trainer. A new lossy image compression format and encoder/decoder designed for resolution independence instead of a fixed pixel grid. I don't know, just cool projects that get people really excited.
I mean, the logistics of organizing such a thing would be a little crazy, since not every type of project is amenable to a large number of developers working in parallel, and you'd need a kind of domain expert and lead architect on each one. But it would be so, so cool...
