someone is working on a reddit api compatibility shim so reddit apps could connect to Lemmy without redesigning their apps
https://github.com/derivator/tafkars/tree/main/tafkars-lemmy
“Tafkars stands for “The API formerly known as…”, is written in Rust and is pronounced like “tough cars”. Tafkars is an API proxy that allows apps to talk to Lemmy through a familiar API from a kinder time. The hope is that this will make it easy for app developers to support Lemmy with only minimal code changes.” @fediverse
The individual communities, no, but where they are hosted is decentralized.
Might not be a big UX problem. If Apollon or RIF had their own instances, and defaulted the feed to “all,” not local, then the experience would probably feel similar to a lot of folks.
But Apollo’s instance might also have a million+ folks, so that could be a performance problem.
