Blogs I Read: Professional edition: Updated

I thought I would let you in on some of my favorite blogs that I check out on a fairly regular basis.  This is actually a two-part series (a first-time in my world of blogging).  Part 1 will deal with the “professional” blogs I read basically written by journalist or the like, and normally focused on a particular topic that I have an expressed interest in.   Part 2 will deal with my friends blogs that I like to read.  But on to the list.
