I'm still struggling with how to handle this. On the one hand, it makes a lot of sense for it to be public. On the other, I've given up a lot to spend time developing it (including going part time on my day job), and I would love to be able to devote more time to it, which would require making some money off of the material in some way.

I've been thinking about doing a kickstarter, but I'm interested in exploring other models. I don't have a ton of time, and I'm always torn between spending time trying to figure out how to publish/market/exploit the material versus spending the hundreds of hours reading history and math and trying to actually write the curriculum. So far I've just been punting on it till I get this first course done.
