When I visit kbin.social, I see new posts regularly. On other servers posts stay on the frontpage for multiple days. This is also true if I switch their sorting to “hot”. So that is probably not the difference.
What is kbin.social doing differently?
Why are they getting rid of WebSockets? It’s really useful for instant data and is often faster than simple HTTP requests.
You can see the discussion about this here, but the short version is that it’s not scalable, hits apps & browsers like a truck, memory leaks, and live updates cause feed reshuffling which is really annoying
