I totally agree. But in the job market, I have search tools to find the best job close to where I live, within my skills, and in my salary range to maximize my comparative advantage. And don't even get me started on all the tools and advice you can get for the stock market. But there is currently no tool for maximizing the comparative advantage of volunteer work. The good news for me is that there are a lot of similar tools to what I want to do, so I don't have to be terribly creative.

You did give me an idea. Let me edit my post.
