One of the blogs I read on a fairly regular basis is Tim Rohrer's Sales Loudmouth - http://salesandmarketingloudmouth.com.
A recent article about titled Dragon Rider is one of the best I have EVER read - http://salesandmarketingloudmouth.com/2010/01/26/determining-medias-roi.aspx.
I recommend it to every advertising sales manager and advertising sales person I meet.
Have a GREAT week!
