Would it be worth it to require real names, ala Facebook, when using the service and interacting with others online to enhance that trust. Or is the culture of Internet anonymity too much to the point where few people would want to sign up?
Can it be a hybrid, like how GLBSE works? GLBSE says whether or not the asset issuer has provided identity but the issuer can operate under an alias such that nobody except GLBSE knows the issuer's real name.
