I like CNN's new format. It lets me absorb much more information at one time; well, info. that I want to know that is. I usually tune out or ignore the other bits of news that I don't care too much about.
I'm with Siren on this one. I don't often actually sit and watch HNN, and the new format is very visually oriented. I liked the old format much better, this new format is way too close to the format of Bloomberg's news program that it's sometime hard to tell the difference.
