If I want to quickly scan an article, I start by a few opening sentences, then go directly to the conclusion, and if it is not enough I will quickly scan the opening of some paragraphs to look for the most compelling arguments/experiments. I don't see how using something like Spritz I could be more efficient. The point is that you don't need to read every single word, even very quickly, to grasp the author's ideas. Maybe I am missing something ?
