For example... Look at this Facebook post I just took off a friend:
"In preparation for reading Fahrenheit 451, my class did a little social experiment today. While they were working at their desks, I had them quietly move to the board and make a tally mark each time they got a notification on their phone. Grand total for today: 1,687 notifications. That’s 1,687 interruptions to learning caused by cell phones.
"One of the central ideas of F451 is that constant, mindless distractions prevent people from developing authentic relationships and suppress deep thought. Hmmm..."
