Wikimapia is pretty cool.

Santo Domingo Map. Very fast site and you can pan out and into other cities. If you have a business or want to recommend one, you can post it here free:

Wikimapia - Let's describe the whole world!

Yes, the locations are polygons instead of the pin points, and they have more info than in google earth/maps, which has links to the sites but not much more. It seems MUCH faster too, but you can't change the orientation of the map. You can also use it while online, while with Google Earth, you have to open it separately. The locations often have YELP! type reviews, which are a big help.
