Google Map Builder: Good, but good enough?

Being able to show people where things are on a map has become increasingly important as online mapping has improved. With the rise of services such as Google Maps and Microsoft Live Search Maps it has become relatively simple to send someone a map of a location and even directions on how to get there, which has increased the perceived value and has thereby increased the value of mapping and so on.

But setting up maps particularly complex ones for business use is still somewhat daunting. A new service has appeared that aims to simplify this task: Google Map Builder.
