After evaluating last week's interactions, I'm more convinced than ever that my experimental philosophy project is worth doing, but I'm convinced it can't be done on a blog. A blog tends to produce "star-shaped" interactions (which means all the commenters interact with the poster at the center) or "bi-polar" interactions (in which two commenters engage in a verbal dogfight). Project Capua can't work unless the participants develop a "spirograph" pattern of interactions, and I don't see a way to get there from here.
I'd love to try this again sometime, but I think we'd all need to spend at least week together to lay the foundation for the conversation we could have.
