I find the idea of the fediverse fundamentally broken, if not plain wrong. It’s cool for decentralised servers from the same service like Mastodon, but keep it there. Other services have different uses and interactions, I don’t want a lemmy thread suddenly showing on my mastodon timeline. I go to Mastodon for microblogging, and it would piss me off to suddenly see giant posts from some WordPress instance, or thousands of photos from Pixelfed, or a tutorial in video form from Peertube that should be a paragraph on Mastodon.
If I want discussions, I go to lemmy. If I want long posts, I go to WordPress. For microblogging, Mastodon, and for Photos, Pixelfed. Mixing all up brings subpar experiences because the apps that deal with each service are focused, and interaction with anything outside this scope becames awful.
