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.
Interesting. You can also try
https://poptalk.scrubbles.tech/c/popheads. On the website I know there’s a bug where it doesn’t show a loading spinner either, so it may take a few seconds after clicking search for it to show up even though it looks like it’s not doing anything.Lemmy.ml is also inundated with new members right now, they’re actually 404ing for me right now, so they may be having issues connecting.
