I like this idea. We should make a topic like this every month or so, maybe in the fediverse community, too. Discoverability is so hard on the fediverse.

I usually try to populate the main ones, even popular ones such as !comicstrips@lemmy.world or !europe@feddit.de don't have that much content.

I'm taking those two as examples because comicstrips usually makes it to Top of All when content is posted, and Europe is potentially appealing to a large audience (326 users a week)

My favorite cat sub, !scrungycats@lemmy.world.

I created !onskates@lemmy.graz.social, a community for quad & inline skating. So far there was only a single post from someone other than me. 🥲

I’d also like to go much more niche with a community specifically for wizard skating. But considering the limited popularity of skating communities, there is no need to hurry creating that one.

!graphicnovels@lemmy.world

I even posted pictures my entire collection some weeks ago to get things kickstarted but is no moving.

Here are some

• !theNightFeeling@lemmy.world - this community was quiet on Reddit as well, which was nice in it's own way. It could use some more content though

• the various animal communities, like !awwducational@lemmy.world

Most of the ones I created;

!teletext@fedia.io

!yoursinclair@retrolemmy.com

!dtt@feddit.uk

!dabradio@feddit.uk

!beds@feddit.uk

!chiptune@fedia.io

!lemmings@lemmings.world

All of these are largely just me posting! The last two do get occasional posts from others.

Really trying to get !geocaching@lemmy.world off the ground

!sbcgaming@lemmy.ml, used to explore it daily on that other site, but now it hardly receives new posts :(

Honestly? I'm just wondering why there is noone on league of legends related Communities like !league@lemmy.ml considering how active r/leagueoflegends was/is

!imsorryjon@lemmy.world

I created @insect_photography during the migration and it started off nicely. Activity has gone down though so be welcome to just check in if you’re interested or have something to share!

Electronic hobbyist pages for Arduino and Expressif microcontrollers for project help and showcasing protects people are working on:

!arduino@lemmy.ca

!esp32@lemmy.ml

!battlestations@lemmy.ml has been pretty quiet... I miss looking at cool setups and vicariously imagining myself using them.

!miamihurricanes@fanaticus.social

As the name suggests, it’s for fans of Miami Hurricane sport teams. I’m more or less the only poster right now.

There are not enough single game focused communities, and the ones that do exist either have nobody in them, or are just bots spamming low-effort content that don't garner discussion.

!whatisthiscar@lemmy.world - Post pictures of spotted cars that you cannot identify.

!oldcars@kbin.social - for classic car enthusiasts

!swimming@lemmy.world - self-explanatory

!countrymusic@lemmy.world - Country Music

!idiotsincars@lemmy.world - also self-explanatory, a bit more active than the others. Submit your dashcam footage here of idiot drivers

I dont own/mod any of these but would like to see more people active in them

I created !15minutecity@slrpnk.net and it's got some activity but it could definitely use more!

Communities for JRPGs (Japanese role-playing games, like Final Fantasy or Persona).

!JRPGs@kbin.social has the most subscribers so far, but the mod at !jrpg@lemmy.zip has been more active in discussion.

Edit: huh, just noticed the kbin community hasn't updated in a while through my lemmy instance. Known issue maybe?

!aeropress@lemmy.world For all your puckshots.

!admincraft@l.matestmc.ru

the instance is pretty much dead and that means the community is dead also.

The one I created! 😏

!paulthomasanderson@lemmy.world

Android emulation community

!emulationonandroid@lemmy.ml

!emulationonandroid@lemmy.world

sffa.community stands for Science Fiction Fantasy Alliance. It's a small instance focused on Sci-fi and Fantasy in all mediums but its still trying to get on its feet.
