To be honest I like the idea of being able to move my account from a server which is offline to a different one. We should have it with ActivityPub too.
Before algorithms we all used hashtags. Hashtags were very important to Twitter in the before times. That’s how you find topics on mastodon. I have columns set with specific hashtag sets so I can quickly glance at toots about horror movies, birds, retrogaming, etc…
You can also follow hashtags directly in your home feed just like Twitter topics.
It’s really not a difficult thing at all, but people are so addicted to Twitter they always give a halfassed attempt at switching before throwing up their hands.
Before algorithms people said “I don’t get Twitter” and stayed off Twitter. Those same people now just say “I don’t get Mastodon”.
