A recent article by the AP looks at the popularity of the different web mapping services and finds that the winner is not Google Maps but Mapquest. Despite the press that Google maps has been receiving the results indicate Mapquest is the clear leader with 70% of users stating they use it, compared to 33% for Yahoo Maps and 26% for Google Maps. However, the article does mention that the new kids on the block are catching up and that Mapquest is innovating because of it. The moral of the story appears to be that big press doesn't necessarily translate to big traffic to your site.
