I agree with Royalty because of the face that when I was looking at Hosting Directories, they were really clutered (of course with ads) and can sometimes be intimidating to users. Google has a nice clean interface and a very specific search engine. You can find what you need in a snap! But if you know how to work with both, you put yourself at an even better advantage when getting your name out. Hope that helped.
