Lemmy is active enough as is and the apps are great but I still have that unfortunate ingrained habit where I keep coming back to abusive Reddit.
I should instead focus my attention to contributing to the conversation here, sharing articles and creating original content.
I’d say ani.social is in need of a retro anime community. Go create one! I might join it, even. I hear people talk about the Melancholy of Haruhi Suzumiya (2006) like it’s retro now and I feel really old.
