Firefish née Calckey is a microblogging platform like Mastodon, but that’s about all it has in common. Firefish has extra features like emoji reactions (like Facebook’s, but you can use any emoji, including custom emoji), quote posts, and better support for deep threads (it displays replies in a tree view like Lemmy or Kbin, unlike Mastodon which tries to linearize them and makes them a confusing mess). it also supports text formatting like bold, italics, headings, custom link text, and even animations (don’t worry, they don’t autoplay). it’s even themable, and supports migrating posts from other accounts so you don’t have to start over!
