The article mentions of days when you were anonymous, getting to know strangers through common interests and exchanging ideas. I do miss those early days. For me, social network stopped being social as soon as reasonable assurance of anonymity when out the window once companies started pressuring people use their real identity, and that became the norm.
When everyone's anonymous, anyone can speak their mind without worrying about offending anyone. When everyone's identified, only the crazies and extremists truly speak their mind - they don't care about offending anyone. You might end up with a mix of crazies and extremist "thought leaders" with packs of quiet followers - a suppression of the moderates and deep thinkers.
It didn't work. It just deterred me from commenting at all, and when I did comment I think I was more terse and condescending than usual. I'm not sure why, but I wonder if maybe in anonymous forums I kind of just assumed a lot of the stupid things being said were by edgy teenagers. I was inclined to be patient with them or write them off since I just sort of assumed they were too young to know better and would grow out of it. But once you see the profile pictures of the people posting, and they're grown ass men who really ought to know better, it's much harder to be nice because you know these peoples' horrible beliefs have consequences.
