This is a rather useful wee site: WoW Headlines.
It's much like the Warcraft AllTop, but broken down by classes instead of blogs. The majority of the subscriptions in my RSS reader are druids, bar the few dozen friends I've also added. This is a really handy way to keep abreast of discussions going on amongst the blogospheres around other classes.
Nice work from the person behind Alterac Volley, I believe.
