I have been on the edge with twitter and reddit for a while and I have finally deleted my accounts that I have had for a very long time there. They are no longer the places I used to know, even more so with twitter. I am ready for my new time here and on mastodon.
First time poster. I'm on lemmy.world but found not many of my channels like I have on Reddit. How you all find your niche subs that are bigger than 30 people?
Gotta post content and engage with the small communities to help them grow I guess. Since I've started a few weeks ago I've seen new communities spring up everywhere. Hopefully in time whatever you are missing will come to Lemmy.
Start with Lemmy Explorer (https://lemmyverse.net/) and look for communities you're interested in, and subscribe to them (it helps if you hit the little house icon and tell it what your home instance is)
Sort posts by "all" and look for ones that seem interesting, then look at the community those are posted in and subscribe.
Do that for a bit, then you can sort by "subscribed."
