The fediverse is the network of federated decentralized social media using activitypub to connect. Lemmy (the software on which chapo.chat is based) will be in some months part of this network.
What do you think about fediverse ? Are some of you using Mastodon as a twitter replacement ?
Why would I care that it's the same user. I only care about the content of their post. Why would I care to know that bilb on chapo has great posts on chapo.chat but has absolutely the worst taste in teaware patterns? It's not worth the technical infrastructure and code to implement
If you don't care to socialize beyond reactions to content, then yes, identity doesn't matter. I like the idea of creating and fostering relationships between people though.
because my identity is metadata I'd rather control. federation allows me to set up my own lemmy instance (for myself, close comrades, etc) and choose what gets shared with other instances.
fully separated identities fragments that data instead and splits control over a bunch of parties.
