would love to get @Michael Edward Johnson's responses here

I'm working on a site that lets people map the logical relations between ideas in a massively collaborative environment.

My background is web development (I run the site songlyrics.com) and philosophy (I'm in a MA program at UChicago doing philosophy of language, logic, and epistemology).

The project is currently just shy of a working prototype. The idea is to do things differently than sites like debategraph.org, where arguments are organized hierarchically. We want to simply have propositions, and logical relations between propositions. Our aim to develop a single contiguous map of ideas. A graph rather than a hierarchy. If anyone's interested in hearing more, let me know.

Side question, does anyone have any data on how big the community is here at LW? I'm applying for a social business competition and I consider the users of this site to be squarely positioned within my target audience.
