This is such a great idea. I think many people when looking at the idea of creating a course, think it must be massive and include every detail of every topic. So many time though people are looking for information or how to do something on one very specific topic.

I think it can also be a great idea to use this as part of your funnel. It helps introduce people to your way of teaching and products. A small short course can be much easier to buy then a big course at first. But once they know you can deliver on a short course, it makes it much easier to buy a bigger longer course.
