I thought a lot about creating such a system and how it would look a number of years ago, but never did make any good progress on it. The point where I got stuck was to take a particular blog post with lots of debate in the comments and try to dissect it in different ways and see what ended up being the most useful. I found I didn't have the focus to do so.

Anyway, there's Truth Mapping, which I think sucks for quite a number of reasons.
