Jopsy asserts "MUDs are living anthologies of kinetic poetry, rife with complex characters and fantastic settings, where the audience is involved rather than passive. It is a form of expression that has probably become more prevalent than poetry." and "MUDs are simulations or models in which people naturally and unconsciously model themselves and their ethics, manners, expressions, roles and identity. I doubt there are better tools out there for self discovery."
