The same could be said about many articles posted here. Personally I only read the first few paragraphs before closing the page. Anyway, I upvoted it because it offers something interesting which I was not aware of, and made me curious as to its change. (I didn't downvote you, but I assume it's because the comment doesn't really add anything. The complaint isn't that constructive, and is not aimed at the right people. I think most of the people here can figure out how to read which includes determining it they should continue reading something, and not fall into the sunk-cost fallacy of "I atarted reading this, so I have to finish.")
