A large enough userbase to support more niche topics. On Lemmy, like a lot of small communities, people tend to put the cart before the horse. They make places to share content for very niche topics but there aren't enough to warrant it. Plus sometimes you have mods in certain relatively niche groups that will remove content from their community because it is off topic, but their volume of posts is nowhere near enough for the occasional, technically off topic post to really matter. I see it in Discord servers too. Some places have more channels than users on the server. People get obsessed with categorization.

Support from Nebula creators.

Nebula doesn't have its own comment system, so it's up to the individual creator where, if at all, they engage their viewers. Most if not all I've seen mentions reddit. Some may be on Bluesky too, but as far as I'm concerned Bluesky is just another proprietary platform that can turn into a monetization driven project.

I really want to participate in the jetlag discussions, but I don't want to log into my reddit accounts ever again. So I'm left with the nebula community here, which is better than nothing, but we're like 5 accounts that participate monthly.

An active stopdrinking subreddit, and more active Sports sections.

Poem guy

Better specialized subgroups they can actually talk with people in you don't have to listen to everybody constantly whining about the billionaire class and how they don't get a chance to do anything in their life.

Content and the number of users. Good lord there are so many dead boards on lemmy.

Easy way to look at the context of a reply.

More apolitical communities

Ability to turn off reply notifications on specific posts.

Being able to clear all notifications. It's a basic-sounding feature, strangely isn't implemented.

Better UFO/UAP communities. It's pretty barren around here as far as this topic goes.

the niche communities over there, replicated here, but without the number of users some are ghost towns on lemmy. with them forcing popup logins piecemeal, we may get a boost.

also people scattered way too much to other similar platforms, when one instance shutsdown which is problematic.

also some politically heavy instances ban like they would on reddit.

More users. The scalability to accommodate more users.

Other than that, Lemmy pretty much has everything.

More sumo fans. Of course then I probably wouldn't be putting in the effort to do daily match recaps, so at least it's inspired me to create more content, which lets me talk more with the fans we do have.

Active communities. Some of the comms for my interests technically exist, in that they get one post every third month that gets 2 upvotes. Despite everything, these communities are still thriving on Reddit. Yet for whatever reason, any attempt to replicate them here fails. Smh

90% of the answers in here boil down to more users.

More users in smaller niche communities. Lemmy has less users in general, so smaller niche communities are practically non-existent here.
