This looks interesting, I want to start to a young and fresh tutorial platform where there are less competition 
Are there any courses for Python or Nodejs devs? Aren’t there too many projects like that on the platform?
The platform is relatively young, that’s why there’re few courses, and not all of them are useful. It’s high time to start using it because the number of users is expected to increase significantly in the future.
You should create only high-quality content, otherwise, it won’t pass the moderation. The information should be true and easy-to-understand. You can have a look at this course, it’s a good example (Building an application using Hyperledger Fabric - Education Ecosystem (education-ecosystem.com)). It’s very useful and easy-to-understand.
