LLMs have their own biases.
But either way, I want people like dang to be the ones moderating and managing a community - call it "personal bias" if you'd like, but they have a vision for the space, and as long as I as a user think that that vision is of a community I want to be in, then it's fine. If I no longer think it is... I leave.
They won't have personal biases, don't need to sleep (ending the infamous "mods are asleep, post xxx" waves), their prompts would be visible to everyone, and there could be ways for the users themselves to update the space's rules/prompts.
