@pixelfed Why is it important for people to know that a Fediverse exists?
Because just as people can do different things on different websites, they need to know that they can do different things on different Fediverse services.
Most people don't visit Wikipedia expecting it to be Facebook. And most people shouldn't visit @pixelfed expecting it to be Mastodon.
@pixelfed "But why can't we do everything through Mastodon and define function at the client level?" some people ask.
Because servers create boundaries on what clients can do.
Mastodon doesn't support comment control. Other Fediverse server software, like @pixelfed, does.
This isn't to say that Mastodon is a "worse" service, just that there's certain functions that it does and doesn't support -- and a client can't add those functions.
And believe me, that's fine!
