Hmm there's not a big fanfiction scene here on the fediverse huh? Or fandom in general. I know there's at least one instance dedicated to fandoms, but last I checked there wasn't much.
I realized recently my main hobby is romance fiction, and I'd love for more of that to be on a decentralized, foss place.
True in my case
Sappho is great btw.
