Great article.... people have to go three comments deep of pure unadulterated ass-hattery to get blocked by me. I'm far more likely to follow people who disagree with me than I am to block them - because that's how you get rid of echo chambers.
I get blocked far more often - some people do like to dish it out and not get a polite rebuttal. Some people like to leave really nasty snarky comments and then block me after I reply in kind.
All in all, humanity is a shit show. Not this article though. This article is great. :o)
