I didn't read it in depth but I have to wonder if it's just the smart phone or more of instant answer to questions and whims. I finally gave in and got a smartphone but I think my brain drain has been going on for years--always in front of a computer, so juggling work, internet forums, email, hitting wikipedia and the like is something I've done for like ever. One doesn't need a smartphone to get addicted to instant stimulation--the smartphone just cuts the tether.
Personally I'm not sure that BITOG and other forums aren't a form of social media. It's just not quite as inane.
