Most of them are poorly written or written in a way to make money.
That is
* clickbait titles when the bulk of the information in the article could be summarized in the title instead
* lack of introduction / thesis / abstract at the beginning summarizing or outlining the actual content
* meandering content with no clear overarching goal
* content padding – lots of words addling little information
So why should I feel bad about not finishing things I think aren't worth finishing?
