An interesting fediverse quirk. On Mastodon, you can change visibility midway through a comment thread.
This makes sense because Mastodon is a Twitter-like microblogging platform and each response is a post in its own right.
But this is a federal system and your toots may be going to something that isn’t Mastodon.
This, that you are reading now, is not a Mastodon post. It’s a Friendica post. Friendica is not Twitter-like; it’s Facebook-like. That means that a post includes all responses as comments on that post and not first class posts in their own right.
Which means you can’t, e.g., change the audience midway through a comment thread, even if the people you’re replying to are on Mastodon, because the idea of changing the visibility midway through a comment thread is absurd in Facebook-like parlance.
As different fediverse protocols become increasingly popular, we’re gonna have to het used to these quirks.
