I didn’t see an #Emacs community on lemmy (maybe I didn’t know how to look, or didn’t look hard enough), but Emacs has always had a strong presence on various social media sites. Here’s one for the Fediverse!
Please feel free to boost this community, invite other Emacs users, and get some content going. If another Emacs community rises to the fore, perhaps we’ll move there … but for now, here’s a home for all things Emacs.
It looks like there is lemmy.ml/c/emacs, which I was unable to discover using the search bar on my instance.
Usually you have to search, wait a little while for it to populate and refresh. It should then show up. Unfortunately you do need the link for that.
But https://browse.feddit.de/ is a fairly good search engine for lemmy communities.
Yes, with the link direct it works, but searching for terms such as “emacs” and “elisp” it did not show up. Lemmy does not seem (as far as I can tell, so far) to federate things like hashtags, which is how Mastodon finds things like this. At the very least, it feels like it should be federating community names!
