Mastodon is the federated equivalent of twitter the same way lemmy can be considered the federated alternative of reddit. That's the nice Twitter alternative you are looking for.
This would be great but most people will not care and sacrifice data for convinence. Wish the government cared as much about us big tech as they did TikTok.
Ive been using wefwef since the loss of Apollo / reddit, it works pretty well and allows to sort posts or comments accordingly. If you want to see what’s going on right now you can go to your all feed and set it to the most recent posts. Also has a bunch of other sorting options. Like hot and active.
