There are multile !asklemmy and multiple !technology and multiple !worldnews and multiple !fediverse… the list goes on.
You really think they’re all just gonna create an instance together? They’re seperate because they WANT to be. That’s the fediverse for you. Not to mention that these instances would STILL have their own individual communities; which you would likely see across your feed at some point if you view “all” posts and not just local or subscribed. It’s easier for you to just block them and call it a day.
I dabbled with Jerboa, Thunder, Liftoff, Connect, and wefwef.
I like Jerboa the most.
