You know I'm one of the rarer people pushed here because essentially all the communities are taken on Reddit. Every name for every possible community is captured. The Lemmyverse offers way more opportunity for community building.
Yeah, I do like that you can just pick another instance to create your community. Like, yeah, it has disadvantages, too, in that new users may need to sign up to multiple communities, but it makes communities a lot less 'serious'. You don't need to agree with the moderators of every community, because you can choose or create a different one.
I do also like that you can choose to only subscribe to e.g. one out of three communities for an interest of yours, in case you don't want the firehose of all posts ever shared about the interest.
Actually piefed does a lot to mitigate this. Using its interface. If you go to any Community where an article has been crossposted. If you go into the comments there. It shows the comments from all communities on all instances it was cross-posted too.
