Glad you made it over to slrpnk :)
I love that youre creating a story based around spreading fediverse principles.
I do think the lore works really well in your story. Fungus as an alternative mode of functioning works well in the setting you created for the story & parallels alternative communities like lemmy or irl collectives.
Maybe expanding some of the sections could help with grounding some of more abstract areas and would give more space for exposition to make the work more approachable for mainstream readers.
