orangesoda.net is online
My friend Lang and I have started maintaining orangesoda.net together. We'll be using it to host projects and bits of code we create in a permanent location.
As an experiment, we're writing the site in Org Mode. We've both been using this to organize projects at work. It has built-in exporting and publishing features and is a natural fit for tracking a project's status and maintaining documentation.
The source is available on github.
