Loomio

A collaborative proposal creation site and the open-source software that powers it.

Victorykit

Victorykit was/is Aaron Swarz's political tool.  (I wanted to call it a platform - but it's not a political platform!  ... Or is it?)  I think it may have been written based on email he'd exchanged with Cory Doctorow (fourth paragraph here).

Madison

Hmm.  A collaborative document creation tool.  This is where democracy's going, folks.

Open Government

Another post about open gov - "Dear Internet, it's no longer OK not to know how Congress works", which is clever, but instead largely about disrupting the system with better political software, which I like.
