<Nim> A little bit of advice for any newcomers who can somehow see this: The fediverse doesn't look the same to everyone.
Leaving aside defederations, which vary wildly between instances and have been repeatedly likened to warring kingdoms, the way posts themselves are shown is not the same.
For instance, Misskey-flavored markdown — a text formatting language robust enough that artwork using it is fairly common — is baked in to misskey, it's forks, akkoma, and some mastodon forks. A post that relies heavily on MFM will look very different when sent to an instance that doesn't support it. Akkoma also has regular markdown and BBCode.
Another thing is quote boosts, which *keys, akkoma, and some masto forks have had for years, but mastodon only recently implemented in a completely different breaking manner.
Akkoma, *keys, and masto forks have unicode
and custom emoji reacts
, while vanilla masto does not. Emoji reacts replace likes in most keys, and how this works with regular likes changes from fork to fork and has sparked discorse on multiple occasions.
Even how timelines are rendered can be different; Akkoma will show you posts buried deep in threads, but most *keys by default will only show you OPs and when someone replies to themselves; *keys will show you every boost of a post, akkoma will usually only show you a post once.
Mastodon caps the number of attatchments at 4, while other software can go as high as 16. Mastodon has a hard-coded twitterlike character limit, some other softwares can go up to the tens of thousands of characters. And *key instances have an option that gives you cat ears and nyanifies your text.
And no two softwares implement hashtags the same.
Sharkey can share flash games with the ruffle plugin, and some instances of various software are modded with the ability to play tracker music
And this is only the microblogging software; there are image sharing softwares like Pixelfed and video sharing software like Peertube.
GoToSocial and Friendica are also microblogging software I've seen around, but I know very little about how they compare.
Now, I am not a fedi dev. These are based on what software I've used, and what others have said, and could be out of date, but it gets the point accross.
