Domani Spero at Diplopundit ("Just one obsessive observer, diplomatic watcher, opinionator and noodle newsmaker monitoring the goings on at Foggy Bottom and the worldwide available universe") provided a run-down on issues relating to this appointment.
Money quote(s):
"The Assistant Secretary of State for Public Affairs is the head of the Bureau of Public Affairs within the United States Department of State. Typically, the Assistant Secretary of State for Public Affairs is also the official spokesperson of the State Department. The Assistant Secretary of State for Public Affairs reports to the Under Secretary of State for Public Diplomacy and Public Affairs ("R").
On May 26, 2011, the State Department announced the appointment of Ambassador Victoria Nuland as State Department spokesperson. She takes over PJ Crowley's old gig at the podium but unlike PJ, she will not be dual-hatted as Assistant Secretary for Public Affairs."
Those two jobs probably should be kept separate, if they're going to be done competently and without burning the office-holder to a cinder.
"(C)an you really say "no" if POTUS or VPOTUS asks you to serve in such and such a position? And if you say "yes" does that mean you're also saying goodbye to your career as a professional diplomat when a next administration is sworn in?"
It's nice to see a career officer not being tarred by the faithful execution of their sworn professional duties under a different presidential administration.
As of last month (if not earlier), Amb. Nuland was on the job as spokesperson.
