Well I’ve seen some places where people incorporate Blue Post (Official post made by Blizzard reps on the official forums), but I’ve yet to see someone break it down by a specific Class. So mine does! You can see it in my side bar.
I figure most of my readers will be more concerned what is posted in blue on the Mage forums then others. Following the link will land you on WoWBlues.com. Not the only “Blue tracker” service out there but I think I like the way this one is presented best.
I’ve also added a few more Mage related blogs to my Mage links in the side bar as well. If you know of one that I’m missing (and they still actively post) let me know and I’ll get them in there as well.
