PressThink’s Blue Plate Secial names them, and explains the criteria:
The point system worked as follows: Five Blue Plates, working closely together, examined the blogging sections of all 100 largest newspapers, and narrowed the list to 20 nominees for ‘top’performer. We knew in a general way what we were looking for: very user friendly, high quality content (writing, editing and images) and a grasp of blogging, a sense of ease with the form.
The full Blue Plate Special team of 18 took a week to pore over these 20 sites. Voters assigned 10 points to their first choice, 5 points to their second, 3 points to third, 2 points to fourth, 1 point to fifth, with one honorable mention permitted.
The Houston Chron gets the top nod.
