I was talking more about general audience. I understand that people who read SciAm won't magically switch to the Twitter and YouTube videos as their main media for public discourse. P.S. Not related to the main topic, but you might find it interesting. For the past few months I was reading books exclusively on Kindle but recently I had to buy a paper book (Coders At Work) and the experience is awful so far. I can't highlight and save quotes I like, I can't make notes, I can't quickly look up a word definition. But the worst part is that with Kindle I forgot how difficult and almost impossible it is to read while standing in the train or laying in bed. So, although Coders At Work is a very interesting book I can't wait to finish it and return to my ebook reader.
