Twisted Nether has posted a WoW Blogs Wiki which you can peruse or even add to yourself. You can look for general WoW blogs or class and spec-specific blogs. So you're jonesing to find out more about playing a Prot Warrior? You've got seven to choose from on the list. You can also look for topic-specific blogs. There are four RP-oriented blogs on the list and three about guild management. There are even more than a dozen podcasts to subscribe to, including ours, of course.
While you're there, add your own favorite blogs into the correct category so they can get more exposure. Looking for new RSS feeds is a great pastime on Tuesdays during the WoW maintenance cycle, too. When you come back, give us a full book report and a diorama for extra credit.
