Wow you're really plugged in to the fediverse. Which of the systems you run are the easiest? What aspect is missing in the fediverse that you hope will get developed in the future? Also, how did you get to grow mastodon.world so much? I'm new to this world, there is a lot to learn :-)
Well running them all is easy, I mainly use Docker for running them, which makes it easy.
I just hope all platforms will be developed to maturity, and they will all follow the activitypub standards so they can communicate with each other. Now, some platforms implement features a bit differently from eachother.
So now with the size of lemmy.world and mastodon.world, I'd say you're probably the biggest admin on the fediverse outside of gargron and his giant mastodon.social instance. And easily the most diverse it seems! Interesting!
I'm finding Kbin more interesting than Lemmy on trying both. I can do all the Lemmy stuff but also follow people, microblog & various other things on Kbin that Lemmy doesn't do. Especially Kbin sees posts from around the Fediverse, Lemmy just sort of only sees thread types and gets no content from most of Fediverse, which seems a bit closed and sad. My feeling is Kbin seems quite a bit more integrated in to the Fediverse. Rapid dev pace is always appealing too. Just my impressions so far.
