Does that mean an owner of a website with deep pockets can easily dominate a category?
Yes. In reality, owners with deep pockets are in a better position. It is possible for a website to contribute a million dollars and stay in the number one position for eternity, but this is very unlikely. A more likely scenario would be having a popular blog with a million visits a month linking to the CDH Productions directory. As a result, the contributions increase steadily over time, keeping it in the number one position solidly.
