Reddit has subreddits. What does Lemmy go with?
My personal vote is for lemmings!
Edit: I am personally leaning towards Sublemmy now. It retains the context of being a forum under the general sphere of Lemmy and the connection to Reddit lets people know immediately what Lemmy is about. Thanks to @[email protected] for the comment!
No one will connect a generic term like community to Lemmy. This kinda hurts the awareness of it as a service people can use. Having something more catchy will at least get people asking.
