Difference between pinax.apps.accounts, idios profiles, and django.auth.User
Profiles are meant to be used for public data, or data you'd share with other people and is also more descriptive in nature.
Account data are more like settings for you account that drive certain behavior (language or timezone settings) that are private to you and that control how various aspects of the site (or other apps) function.
What's the difference between pinax.apps.accounts and the idios profiles app that were installed with the profiles base project? 
As I understand it, the contrib.auth should be just for authentication purpose (i.e. username and password), and the existence of User.names and User.email in the auth model is historical and those fields shouldn't be used; but the distinction between accounts and profiles are lost to me. Why is there pinax.apps.account and idios?
