Social media is addictive in direct proportion to how fun and interesting your friends are. This is a real problem for me.
On the other side of that equation: my social media experience has been greatly improved by some blocking. Some people seem to think blocking is somehow unethical, like a cousin of censorship or intolerance. I think that’s absurd: there are people I avoid at a party, and there are people I avoid online! Nothing more to it. Life is too full of people I enjoy to waste time on anyone else.
