So much this. I am genuinely concerned about the direction of discourse and society in general with the way mass communication on the Internet has played out. Just look at how the damn president of the US communicates in tweets - short, authoritative and usually inflammatory. After that, all other conversation is drowned out by Twitter rolling responses in to another view.

The build up of these echo chambers and extremely brief communication patterns contributes greatly to polarizing people on all kinds of different issues. It's really terrifying to me.
