Well, I know I am on the unpopular side on this subject matter (Not personally directed at you, or anyone specific.)
However, catering to lowering the average attention span is not something I want to contribute to.
My values are not for sale like 99,99% of the majority of content creators are, they will do anything and follow any method just for the views.
I am not by any stretch of the imagination close to being a successful content creator, but I just despise the notion of catering to the lowest common denominator - e.g. short attention span in this case.
