I love the vueJS framework, and I'm looking for a side project. So I was thinking: maybe my side project could be to teach people vueJS. Something like: start a blog, build an email list, and later sell an ebook. And I have 2 main questions:

1. How can I make sure people are interested in this before I actually start creating content on vueJS? Basically how to validate the need for vue.js tutorials?

2. And what is the best format to teach vue.js? Written tutorials, youtube videos, one-to-one teaching, ...?

Thanks for your help!
