Twitter? Try going out to dinner without your phone. It goes way deeper than any single social platform. The way we relate to technology has become so weird.
I don't know about you, but if I go out with someone for dinner and that someone is constantly on Twitter with their phone, I consider that terribly rude.
And every time you think of reaching for it, think “what evolutionary desire was I about to short circuit, and what important aspect of being a human does that circumvent?”
