Don’t you think that a sign of a vibrant framework would be the presence of paid artifacts?
It was a case in 2014 and later. Now I cannot see any course or book later than 2018.
I also really miss the coherent structure the Meteor was at that time.
Now Meteor has a lot of flexibility, but probably that’s why it is difficult to describe it in a single course or book.
But that’s why they are now necessary more than ever )
