Further devs like @gruber over-estimate the dominance of Mastodon.
Certainly, in terms of the Fediverse, Mastodon is huge.
But PeerTube and Pixelfed are nothing to sneeze at either.
PeerTube has 306,337 users. That's not as many as Mastodon.
But PeerTube's userbase isn't anything to sneeze at either.
What's more, just like Mastodon, PeerTube could grow. Especially if a black swan event happens with YouTube -- which is feasible!
Another thing @gruber perhaps doesn't consider is that Mastodon isn't the only Fediverse platform that's growing.
Pixelfed more than doubled it's userbase during the past year.
* Feb 2022: 73,100 users
* Feb 2023: 153,486 users
This is despite the fact that there was no Instagram migration!
So why are so many mobile devs just ignoring Pixelfed?
