Having to install a browser extension makes it a hard no for many, the most annoying thing for me is there's no app like Tweetbot for Mastodon that's even like 5% as useful.

I know many people used Twitter.com or their official app, but many people find a simpler native app experience much more useful.

That's why you see Mastodon customer support here and on Mastodon itself by the techies here just for choosing an instance and even explaining why it is all slower than Twitter. For example: [0]

Normal people do not care enough to go on a safari hunt for finding instances, user names of those claiming to have left Twitter or deleting their accounts or even bothering self-hosting just for a username on their own instance.

It's frustrating that the web platform doesn't accommodate federated services like Mastodon that span multiple servers very well, but those are the cards we're dealt. It does work, it's just not ideal.
