Hello guys,
Two year ago I created the free, open-source Babuino Project (http://babuinoproject.blogspot.com), and now I just launched Creative Minds community (http://c-minds.com).
Creative Minds is a collaborative knowledge building environment, where people can discuss about electronics, programming, science, technology.
Blogs, groups, forums, chat, messaging, video and photo publishing are available for users to build and share content.
In addition to the social side, the idea is to make Creative Minds a community where members can contribute to projects under development, and start or publish their own projects.
