We need to capitalize on the decentralized nature of the Fediverse and Lemmy instead of having everyone joining one instance
But honestly, social media naturally benefits from everyone being around the biggest totem pole. It means we can randomly run into people and topics and communities that we never knew we wanted to engage with.
If we decentralize, we need an already established community-web, or a very specific plan for which to find in the future. Plus, I’ll be honest, between Mastodon, Lemmy and (now) Firefish, I can say that finding communities on the fediverse is annoying in all the right ways to make someone just go back to Twitter/Reddit. I can’t blame people for not wanting to engage with that.
But, importantly: Most users being on a huge central instance solves that problem. Yeah it goes against “the spirit of the fediverse”. But for the user, it has effectively only upsides.
