Actually not a bummer in my opinion, let people sort into different platforms based on their interests like we used to do with forums.
A fragmented internet is a better internet
that’s not how the modern internet works and unfortunately i am forced to be on facebook because all 4 of my hobbies no longer exists outside of it.
if people moved to the fediverse instead of bluesky or such, then we’d actually be able to have a fragmented internet again - due to how the fediverse interconnects through federation.
which i think is the best selling point the fediverse have - no longer would users need to be on multiple services, they could just be on one, and still interact with the services across the fediverse. but unless there is a mass-migration of one single service to the fediverse, such as people choosing mastodon over bluesky, to be the dominant service - it’s just never going to happen.
But it’s not fragmented. Mastodon is still the odd “vegan” option while BlueSky is becoming the main Twitterlike platform. Mastodon is still coming out the other end mostly the same.
