Since early August, I've been able to tell people that I've been busy "saving the world"--Saving the World at Work, that is. I've teamed up again with the fine people at Rapture Studio (they did the excellent design and we worked together on the spec) to develop this social networking site related to the ideas in Tim Sanders's new book. For a project of this size, and of this compressed time frame, we turned to the CodeIgniter MVC framework to gain additional leverage. Go on over and take a look.
