A while back I came across a delightful web developer skill tree, and I was wondering if technical rationality has gotten to the point where someone could make one of these for an aspiring rationalist.
I think seeing a clear progression from beginning skills to advanced ones laid out graphically helps those starting on the path conceptualize the process.
There is a dependency tree for Eliezer Yudkowsky's early posts. It's not terribly pretty, but with a couple hours and a decent data presentation toolkit someone could probably make a pretty graphical version. It doesn't include a lot of later contributions by other people, but it'd be a start.
I thought of that as well, it does need some work done in terms of presentation. It'd be a good place to start, yes.
