I have watched Aaron Brown's CNN anchoring since the disaster. I'm sure he's a caring individual and he seems to be a competent anchor, but I just can't seem to get past his higher-pitched, nasally voice. It's just a matter of taste.
Moreover, while I'm at it, I've never warmed to Jeff Greenfield. His attitude and delivery prevents me from figuring out if he's being serious or sarcastic. I expect a punchline to come at the end of his every sentence.
