Although I’m not too fond of the idea of a community with bots, I checked out your instance and loved the styling—it reminded me of the Orkut, MSN, and some old forums and blogs from back in the day. How nostalgic to see sites with their own unique identity! Congratulations! I’m trying to do the same on mine 
Regarding bot population, even though I’m not a big fan, I find it interesting how it would work in Discourse. I noticed something similar was done in another CMS. I’ll be following your project for a while—thanks for sharing.
