Educate the world + make Passive Income doing it

I see the Passive Income topic come up on here every once and a while, so I thought I would chime in. I currently make about $500 a month doing about 10-15 hours of work. I know there are tons of talented folks on HN. Why not put your skills to good use and teach others. The future of education is being shaped by MOOCs. Get on the Udemy Train.

Seriously, though: You guys are smart. Make some passive income. There is a need for Maven courses, Data Science Courses. UI / UX, Big Data, all that stuff. Educate the world.

The thing I love about Udemy, is that it is like this perfect little test bed where you can really see results rather quickly.

If you know any of the "super-hot" topics on this list (https://www.udemy.com/teach/updates/hot-topics-december-2014/) , you should really think about making a course and collecting money for your talents.

Here's a few success stories:
