I’ve already started seeing a lot of redundant communities being made here that have already existed on other Lemmy instances, and lemmy.ml is at risk of centralization and overload, so now is a great time to raise awareness of other instances.
For science topics, mander.xyz has a lot of good ones set up, and !solarpunk@slrpnk.net on slrpnk.net has been great!
edit: for new users - you can type ! to begin autofilling a community, even for ones on other instances, like I did for the solarpunk community above. It may take a few seconds for the autofill results to show up if you have a slow connection like me.
Do you federate with Beehaw? I have a 404 every time I look for a blahaj.zone community from Beehaw :(
I’m on Beehaw and managed to join this one ok. I think there’s a delay when the first person tries to search for an instance, before it actually shows up in results. Not ideal but maybe try it again now?
