I don’t find her announcement mode strange at all.
In fact, I find it a lot more appropriate than Christie calling a two-hour presser to go over every little detail of his decision.
There is an old notion that people should give important news directly to those who have a real interest in the news. Millions of people who have hoped Palin would run will now hear the news in all sorts of ways: from smart assed Palin haters in all sorts of smart assed ways, and with no notice at all, and on and on.
No, this news should have been given with some notice so that those who have invested time and hope and money in Palin could have heard it directly from her.
