Very much agree with this. Websites rarely require users to choose a unique username nowadays (email is enough) and it's been a pain hacking Django to work like that, since many email addresses won't fit in the username field.

In fact I always hate it when application frameworks make arbitrary decisions at the schema level on how long usernames, real names, emails, street addresses, etc. can be. I always use varchar(254) myself. (Unless using a schemaless db like Mongo where this is not even an issue.)
