Title: Twitter API v1.1

Twitter are phasing out v1 of their restful API. Currently they are conducting blackouts for unauthenticated v1 requests, but they are rolling this out to authenticated v1 requests.

While blackouts for authenticated requests have not yet been announced, its a good idea to upgrade to 1.1 asap.
