I never really got into twitter because of the reasons he listed: way too short messages, echo chambers, and people spouting inane streams of consciousness into the twitter ether.
I don’t see the point of it; I see people with tens of thousands of tweets that don’t mean anything.

That said. I think twitter is great for keeping informed on certain events- for me, esports tournaments.
I also think it’s useful for connecting with people and spreading info about what you’re doing- like OSS projects, etc.
Lastly, it's hard to not be on twitter. It's such a huge social behemoth with a vast number of users, arbitrary limitations or not. There isn't really an alternative besides maybe mastodon if it had more people (doubt it; federation isn't easily grasped or shiny).

Like anything in life it’s about moderation. If you check HN 14 times a minute that’s bad also.
