Why do people insist that there needs to be (for example) /c/politics on every instance?

This is a fundamental issue with the way that lemmy is organized that was identified early. Its a design consideration thats pretty much baked into the cake that each lemmy instance effectively tries to be an entire reddit.

Its a bit of an issue, because this will necessarily dilute the kind of network effect that is what allows social media to be as engaging as it can be. Interesting articles don’t get as much momentum. The interaction is more diffuse. Conversations are more spread out and fragmented.

Its beyond the scope of the current design, and I really do commend the developers for what they’ve built (lemmy as is a great experience); however, a more ‘instance’ based approach may have made more sense based on how we’ve seen things scale. Instead of every lemmy instance trying to be ‘all of reddit’ each lemmy instance would focus on a set of niches (for example, a fashion focused instance would have c/fashion, c/mens_fashion_advice, c/streetware,… whatever); then they would federate to propage these niche across the fediverse.

The Star Trek lemmy instance is an example of this. Its a home for all things star trek. I also tried to start something like that focused around WallStreetBets, but afaik, WSB had almost no exodus.

More importantly, the critical mass to get enough users for the content to be interesting didn’t happen. There were too many competing /c’s across the lemmyverse. So articles get posted, but none get more than 1-3 upvotes because the userbase that would get it to say 5-15 upvotes simply isn’t there.

I really do love lemmy for what it is, but this design consideration is absolutely what is preventing Lemmy from being a true Reddit killer. The structure of federation sets lemmy(s) up in a way that there is an inherent blocking factor to super-connectivity.

However, I can imagine a couple solutions to this that dont necessarily require a full burn down and rethinking of lemmy.

One would be to allow for the merging of communities. Users set up C’s, but if there was some way to do a kind of merge (as like on github), where the two RSS feeds could be merged (as in github). Likewise, it would make sense if there were a way to ‘split’ or fork communties, as in, say you’ve got c/fashion, and some one wants to fork off and have it become c/mens_fashion. This would allow communities to consolidate around critical mass (there are enough posts, comments, etc to represent meaningful engagement), and then also to diffuse that issue latter when it makes sense to maybe split off political memes from say, political discussion.

A second solution would be to allow communities to be ‘transferred’ across the federation. This makes sense in that your ‘local’ community should be comprised of the things you care about the most (fashion, mens fashion, streetware, etc…). This feature would allow niche communities to consolidate into single instances, which will also serve to drive engagement (a user of mens fashion is far more likely to post into streetware and vice versus).

A third option would be to build a super structure to lemmy that allows for the consolidation of multiple lemmy RSS feeds into one. Effectively, user would be able to identify various lemmy communities into ‘supper communities’ that consolidate them under a single heading (a tool to grab up all the 'mens fashion advice /c’s across the fediverse) and deliver it in a single RSS feed.

Of the three of these the third option makes the most sense to me. It requires the least rework of the underlying data structures, and seems like a bolt on solution. However, it also might be the least effective of the three. I’ve no intuition about what that would do the structure of the network or if it would aid in overcoming critical thresholds of engagement.
