What I think could make Lemmy superior to Reddit is the ability to create themed-instances that are all linked together which feels like the entire point. I've noticed that a lot of instances are trying to be a catch-all Reddit replacement by imitating specific subs which is understandable given the circumstances but seems like it's not taking advantage of the full power that Lemmy could have.
Imagine for a moment that instances were more focus-based. Instead of having communities that are all mostly unrelated we had entire instances that are focused on one specific area of expertise or interest. Imagine a LOTR instance that had many sub-communities (in this case "communities" would be the wrong way to look at it, it would be more like categories) that dealt with different subjects in the LOTR universe: books, movies, lore, gaming, art, etc all in the same instance.
Imagine the types of instances that could be created with more granular categories within to better guide conversations: Baseball, Cars, Comics, Movies, Tech etc.
A tech instance could have dedicated communities for news, programming, dev, IT, Microsoft, Apple, iOS, linux. Or you could make it even more granular by having a dedicated instance for each of those because there's so many categories that could be applied to each.
What are your thoughts?
I don't agree. If I like LOTR and giraffes I don't want to create an account on both "instance groups". I want to do like today and create a single account, then subscribe to the communities I am interested in wherever they are.
To me it sounds like you are sort of mixing up community location and community discovery. This is sort of the case right now because instances have a list of local communities but I think that it is best that they are separated. For example on Reddit I don't generally find new communities by scanning the entire list of communities. I usually find them when someone mentions a related community in a comment of a community that I am already in. Or when I stumble across a community when searching the web. When you discover and subscribe to communities this way it doesn't really matter where they are hosted or if they are grouped. You can organically discover things that interest you over time (although I agree that it can be a bit slow to start).
But you don't have to create accounts on multiple instances. You can subscribe, post, and mod communities on other federated servers.
You can subscribe and post on different instances. But, I don't think all pertinent communities should be on one CENTRALIZED instance since that defeats the point of the Fediverse.
