I would have preferred her for a domestic slot like health, but it's still amusing to see Clinton confirmed with only 2 votes against (Vitter and Demint), if only to keep janitors employed cleaning up after wingnut head explosions for the duration of her stay at Foggy Bottom. (Hey it's nasty work, but it's work).
Clinton's got a lot of name recognition and is generally (but not universally) liked overseas. Her husband is, likewise, still very popular. Added to the goodwill Obama starts with, I hope she'll be able to do some good in repairing America's damaged reputation, and the source of that damaged reputation, America's foreign policy.
