I have a lot of project ideas (like many of you) but I have some issues. There seems to be no easy way to find existing project online or to ask people what they think of an idea. I'm looking for a social project platform that allow people to search for projects, to contribute to them and to suggest new projects. It seems like SourceForge and FreshMeat are some of the best way to browse open source projects but the ability to bring new ideas and ask if there is a need for it seems limited since it was build to host open source projects, not help people start new ones and contribute to them.
Is there any kind of online platform that allow people to find, contribute and create projects online?
