This is just a question for idea.
I think that the tutorials should actually be a site like how Orion docs is setup. I am working on a pilot app for tutorials using the example-blog as a boilerplate. An example is a note sharing app i'm working on where the user can actually search notes, it too is a fork of the example blog.
Let me know your thoughts.
