One of the best paths to becoming a better Tank is to study and learn from the Tanks who have come before you. I regularly check my Google Reader — and you should too — to see who’s posted something new on their Tank blogs.
We’ve found a number of Tanking blogs recently and have added them to our link list. You should definitely check them out. Most are specifically about one type of Tank, be it Druid, Warrior, Paladin, or DeathKnight Tanks. Regardless, each one has the potential for teaching something to us all.
