I like the colors and layout. It's simple and clean, which can be a plus. I think the logo needs a little more "pizazz".
Also, you should consider some more cell padding to get that left justified text off of the left margins such as the text on this page (and other pages).
The concept may be good, but I wouldn't take random trips to different sites until I was sure what kind of sites are listed. You may want to say something about that somewhere.
