@zephyr I wrote my observations https://hub.hubzilla.de/wiki/kotking/Fediverse/Home . It’s a really Work in progress and raw, but I mentioned and credited source some questions you have. Still think how to fill Kbin section and as I use Misskey also will be written about… But it’s so much feature bloat that I would need wiki for wiki… Half joking.
@Meowmoth I would say feature bloat. If you need social network message service and want fast loads and less mobile traffic/device resources usage then Mastodon is a king with very tried and true nature. Firefish is fork of Misskey so I can tell a bit as Misskey user. If you want everything in one social service then Misskey/Firefish is the one. Build-in rss reader, memos, gallery, pages, channel for chat like experience, plugins, minigames, likes=emoji that convey message, so… Feature bloat.
