I think one very crucial point is missing from the article that explains a lot of the appeal of lists:

lists give me an idea, or at least the illusion of knowing content length beforehand or very early on.

When i see the first list item and the title says "seven of those", i can gauge my time investment in consuming that content.

It's important that this is abstract, as "500 words" has little intuitive meaning but "4 pieces of roughly this text block" is a very natural way of evaluating my time commitment, subconsciously.
