>There's nothing existential wrong with Twitter.
Elon is removing all the moderation, so it's going to become infested with trolls and bots quickly. It'll be just like email, but without the spam filtering. On top of that, advertisers are pulling out, so it's going to run out of money and implode. The future of this company does not look good.
>Twitter has first-mover advantage. Mastodon is still a tiny thing.
Go back in time over a decade and you can say the same thing about Digg and Reddit. Where is Digg now?
>DKIM and SPF were done. They're widely supported and work as designed.
No one actually uses them or requires them for email.
>Isn't this supposed to be the benefits of centralization I keep hearing about? There are only a couple of parties you have to convince in practice to get something changed?
No, not really. With centralized services, you get stuff like MySpace and Digg. Then, when things fall apart, they implode, and everyone leaves to alternatives like Facebook and Reddit. No one actually fixes problems; it's just like empires: they rise, enjoy supremacy for a while, then fall apart. No one fixes the problems they have, they just get worse and worse and eventually implode, and later something else rises up in its place.
>What good is switching to a known-broken technology?
Don't ask me, ask the Twitter exodus. I don't use Twitter, just like I was never a Digg or MySpace user. The people who value this stuff aren't going to think the way you do. They'll all flock to some new hot thing, which right now appears to be Mastodon (though it's too early to tell if it'll really catch on).
>and in the meantime build it.
Who? Who's going to build it? Don't look at me; I don't really care about this stuff and am certainly not going to invest my time in it. It seems unlikely that some company is going to build a federated social network to replace Mastodon (which volunteers already built, over the course of many years), though they might make a Twitter clone.
