Music Critics in the Twitter Age

I was directed to this by a friend: Christopher R. Weingarten discussing the role of the music critic in the world of Twitter at the 140 Characters Conference. His talk is funny, witty, and very relevant. I think the most important aspect of the talk is his emphasis on the fact that people using Twitter (and blogs for that matter) don't address the "Why?" questions in the explaining why a band/album is good/sucks. It reminds my a bit of this post.
