After all, the one thing that hasn’t changed is us. There are still only 24 hours in a day, we need to sleep a little less than 1/3 of that time, and we want high signal/low noise. We migrate to which ever platform delivers us the highest degree of relevance (call it what you want — entertainment, satisfaction, scintillation) without thinking about it. We didn’t consciously move from Yahoo! to Google, Facebook to Snapchat, it just happened because it scratched the itch a little better.
