Honestly, I don't know much of the differences or if it's even simply which framework they used. It just seems to be two different link exchanges/sharing apps that are compatible with each other. Like, I'm currently on kbin but can see this just fine. I'm not sure what my instance's stance is currently, but there's no need to act beforehand as there's nothing lost by doing it afterward instead of before. I don't understand the people complaining that it needs to happen immediately right now. Just seems so impatient and entitled. Folks just need to calm down. They're pulling their hair out for no reason. No one has been able to articulate an actual real problem with wait and see. Just very vague "meta is obviously evil" kind of deal.
