I think that Twitter might be entwined enough into the OS such that it'd get permissions that other third-party devs wouldn't. I would totally love to be wrong though.
I actually started watching the live stream after they demoed Cortana but going back now and seeing Belfiore demo Cortana:
- He added a show to his queue in Hulu but it stayed in the app
- He said "what's up with Terry Meyerson" and it went straight to Terry's facebook profile.
And I realize that FB has some deep integration within the OS (just like Twitter)
