If your intent is to connect via app, I suppose you’re better off with misskey or one of its forks like iceshrimp. They offer server specific custom reactions and allow crazy code on your posts. I recommend not using them on the web because the pages are HEAVY, like, “did my browser freeze or did it crash?” heavy

Wafrn could also work, it’s more tumblr-like than twitter-like and gets you posts from mastodon/misskey and custom reactions
