I think the more the actor lets you know what he thinks of the character, the less the audience cares - like a comedian who laughs at his own jokes.
If you want to make someone feel emotion, you have to make them let go. Listening to something is an act of surrender.
I'm not sure blogs are necessarily the best place to get a pulse on anything. People want to blog for a variety of reasons, and that may or may not be representative.
