Even just looking through the list of communities I can already see two separate “Fediverse” communities on different servers. I’m assuming the posts aren’t shared. How do we keep related discussion as central as possible? Just hope one wins and everyone posts there or is there a technical solution?
Some folks won’t be able to access some communities due to defederation, and in other cases folks may want to start a community on their home instance for certain reasons. This isn’t the end of the world; probably in the long run either everybody will centralize on the biggest one, or you’ll end up with one or two alternatives that have a bit different culture or focus.
That being said, if you like to read comments, it can get confusing when a bunch of different communities all have high interaction posts about the same topic at the same time.
