Interesting. That's what I modeled it off of (and have been consulting Mint folks about it). The previous (posterous) blog had a banner at the top that was identical to mint's, but the ctr was abysmal. I've been moving around the giant button on the right sidebar to test placements and recently added the 'search for flights' and 'search for hotels' in the footer of each post that have been doing quite well lately.
