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.
Not on an app, mobile on android here.
Oh don’t go to the link, paste it into the search bar from your logged-in instance. (The other one should also have worked, but again lemmy.ml is a bit slow and may be having issues).
This is how it looked to me from the website, make sure “All, All, and All” are selected
