Not "web" but the "attention economy" which tries to lure users into echo chambers and raise outrage in these chambers, so that the users spend more time there and click more (political) ads.

Stay away from the outrage machine. Be polite. Assume your partner in a dialogue is neither a fool nor malevolent. Quench flames. Try to understand, not to prove you're right.

Sounds easy and obvious, doesn't it?
