I used Twitter via TEXT MESSAGE for most of 2008-09.
I'm not sure why I'm saying all this.
I think it's because all the really good stuff in Twitter (@-replies, usable clients) was actually designed and built by users, not Twitter. Twitter, the company, didn't embrace those ideas until very late.
Mastodon and other fediverse remind me of that time, when good ideas could come from anywhere. It's the bottom-up experience that's been missing from the web for years.
We really are somewhere between BBS and Web 1.0
