Given the post here a few weeks ago about tracking people through writing style I actually wonder what the point of usernames is. Maybe it should be possible to have a username so people can activity follow you and see other submissions? And maybe it would be nice if each time you posted it generated a unique username so that it's anonymous? You could still keep e-mail registration/verification. And perhaps still give moderators access to the master accounts in case they need to see if a user is constantly promoting a company or constantly engaging in anti-social commenting.
