The author asserts, "this is the community where experimentation ... to educational approaches is happening the fastest", and I am finding that to be true. The parents are more open-minded and the students are more self-driven.
In fact, it feels likely to me that any dramatic change to the education system as a whole will start with the homeschool community, if it ever comes at all. So, my advice to other education entrepreneurs is that this is a good market to start with.
The author's big conclusion - an impending unbundling of education - is really interesting to me. It aligns with my own prediction (and the basis for my startup), which is that students/parents will have a stronger say in who the right teacher is for them, for any given subject. And, with tools enabled by tech/internet, the best teachers will be able to scale up what they do and reach many thousands of students.
