In the past 48 hours, the world has changed. Again. I had resolved not to write about the killing of Osama (Usama) Bin Laden. But I just read a good posting by a blogger friend of mine, Dana of Bug's Eye View. She referenced several other bloggers who have written, meaningfully, of this event. So rather than trying to come to grips with this event myself, I refer you to her blog. Good job, Dana.
