It's more like Thin is when the consumption is one directional. Like when you browse social media it is one directional. Social media goes towards you and you just experience it, everything is dumbed down into bites that require 0 effort or cognition to consume.

When you read a challenging book it is bi-directional. You will get out of it what you put in and it will be indecipherable if you just let it wash over you mindlessly. So I disagree about creation, I think the effort is what is important.
