[Answer]-How to status update on twitter in django with Oauth

I am not sure about social_auth, but django-allauth stores (and updates) the token on each login, over at:

https://github.com/pennersr/django-allauth/blob/master/allauth/socialaccount/models.py#L82

Then it is simply a matter of feeding that token to e.g. Tweepy (http://tweepy.github.com) in order to post a tweet on behalf of the user.
