John Bellinger, the State Department’s top legal adviser, will be guest blogging all week on Opinion Juris, a blog on international law and politics.

Peter Lattman, my source for this post, wonders “if a Bush administration official — especially one of this rank — ever blogged before?”

If we ever have an Edwards or Obama administration, we’ll see a lot more on the blogging and social media front. Edwards liberally uses blogging in his campaign and Obama today announced via YouTube his initial steps in a presidential bid.
