I bought "fresh news" from
www.woothemes.com and love it, very quality theme. But they also have some awesome free ones available now. Using their classic news theme on a few blogs now too. That being said, I've noticed that CTR is generally lower on those "CNN style" themes...seems surfers get a little cluttered. Similar, similar traffic, similar ads, and CTR is statistically lower than on a more conventional blog theme, with 1 sidebar and a bunch of posts on top of each other. Could just be coincidence though, dunno.
