I've left every other social network. No longer on Facebook. No interest in Instagram or TikTok. But Twitter I've continued to get value from. This is entirely because I'm able to curate my feed. My rules for twitter engagement are:
1. Never look at the algorithmic feed. Switch to most recent or use https://tweetdeck.twitter.com for list consumption.
2. Unfollow anyone who consistently pulls you into Twitter cesspools.
3. Follow the people who you find interesting and who doesn't break rule #2
4. Use the mute and block buttons as frequently as you need to.
5. Block retweets which aren't quotes.
Everyonce in a while someone will link to a tweet in a different forum and I'll take a look. 90% of the time I'm shocked at what the author of that Tweet's experience of Twitter is like. My experience is 180 degrees different.
