In a world where food is fast and coffee is instant, you really don’t have time for long lectures and endless discourses. I personally don’t read the first paragraphs of any article that I read on the internet. (It’s just an introduction, slowly trying to sweep in to the main point. Some of them just beat about the bush.) I just skip to the main points and skim through the text looking for words that sum up the whole point.
There was a time when people used long sentences and big words to sound important (read Pride and Prejudice, Sherlock Holmes; you will know what I mean). But today our attention span is too short and our patience is too little to hold on to lengthy, extensive write ups/ videos/ blogs. So the key mantra these days is: Come, make your point and leave.
