I've recently deleted my ten years old Reddit account because I was getting into fights with everybody, and to this day I can't spend 10 minutes on that site without feeling the need to comment "what the fuck are you talking about you dimwit" to some random poster, while I'm finding much easier to be civil on HN, and while I get my downvotes here as well sometimes, I'm on my best behaviour, and proud of the wonderful discussions I've had over the years.
I've tried getting into Twitter, and I feel I would soon turn into the most toxic asshat on the Internet like many over there are, so perhaps it's best I don't.
To leave Twitter is a question of seconds. To leave Twitter toxicity behind and start arguing in good faith instead of coming up with the smuggest takedown and expecting likes ... well, that takes much longer.
