Why shoot the messenger? Tech is so boring nowadays that bloggers lose their interest in getting exclusive scoops (and Pinterest is revolutionary? Yawn). Also, where is the evidence that Arrington is boring?
Second, the real question is can someone interest some and bore other? if yes, in my case, I found Michael Arrington interesting when I went to his very first startup events at his palo alto home, bu then, as he met success (that he rightfully deserved) became to lecture everybody and became very boring to me.
Again, this is my personal opinion that I wanted to share.
