Anons entering a nickname would be a disaster. Anyone would be able to log out and pretend to be someone else. The point of displaying IP addresses is that it allows you to identify in some respect who is who. If IPs want a nickname, per Dopp, they should create an account. Since two accounts cannot have the same name, this would mean that, just like it is now, one person can't pretend to be someone else by stealing their identity.
