The beginning of the article praises Udemy's student experience.

You're doing just fine. I'd suggest you polish your own platform use it to showcase what it can do and charge a fee if others want to use it as a service. Competition is good for everybody, both the users, the course makers and eventually for the companies because it keeps them sharp.

great article, lots of good insights!

For what it's worth, I thought the article was well written and useful.
