I've only been on Twitter for less than year. I mostly follow journalists, some publications and a few industry experts. They are mostly rational people who post insightful things, but a few will dip their toes into nonsense takes on society or just feeding trolls who bark at them. I just unfollow. I found that my follows list topped out a little over 100 and just stopped because I would delete as quickly as I added. I never post and have no followers.

As someone who deleted Facebook after maybe two years on the platform and never took up anything else, I find Twitter to be slightly useful. I get insight from a handful of people for whom Twitter is their best outlet. I use it very much as source of information. It sucks as much as anything else when it comes to discourse. For my usage, I would see Twitter moderate content much, much more strictly than they do now. The most valuable creators don't come within 100 miles of violating any ethical boundaries and I'd reckon the vast majority of readers (and ad clickers) don't post much at all and will be completely unaffected by any moderation rules.
