This is one of the reasons why I love the blogosphere so much.  You've got people out there fixated on one topic or another.  One of the blogs I read regularly is Homeland Security Watch, a serious tome that puts the microscope on the Department of Homeland Security (DHS). 

And this is where I learned that DHS Secretary Michael Chertoff has been blogging on the DHS web site since Sept. 9.  He calls it a leadership journal.  You can go here to see it, and you can even subscribe so you don't miss a word.
