There should be a kind of “sorting hat” personality test to attract the interest of prospective Lemmy joiners. People who love solarpunk stuff, for example, would easily find their home in slrpnk.net. Set a link to it on sites like join-lemmy.org to make the fediverse more approachable to casuals.
New user puts on hat
“Tankie!”
Next person tries on the hat
“Furry……I mean Linux user.”
Final user puts on the hat
“German!”
“But I don’t speak German.”
