@pixelfed I've had a number of people say to me, "Mastodon is a synonym for the Fediverse."
That's only true if you never leave Mastodon, and believe other services work exactly like Mastodon.
For example, look at this feed. If I showed this to a complete noob and said, "This is Mastodon", they would be completely confused.
And that's because it's actually not Mastodon in any logical or meaningful sense.
@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.
