CodeDoor is a way for programmers to leverage their open source contributions to freelance work. (Note: I'm the founder of CodeDoor)
I would also like to make something sort of like a web browser, except its based on a distributed hash table or something so that it is totally data-oriented rather than server-oriented, and instead of HTML and CSS its markdown (with embedded SVG) and optionally RDF (using N3) and optionally a sandboxed Go application that is compiled on the fly. Also the applications aren't restricted to a browser window but have a security system and access similar to that available on mobile.
Or a mesh of user-defined 3d worlds built on WebRTC and WebGL with portals and multidimensional overlays.
You can build any type of app you want on top of Tent.
See the hosting provider Cupcake.io to get a working Tent account: https://cupcake.io (say ^bnb.cupcake.is sent you!)
Just because it seems like a cool project in need of more help. It really does depend on your interests, of course.
