I totally agree, and yes please answer these questions, as I'd be interested to know the differences in quality among the respective teams, their methods for evaluating edits and how they perceive each other.
Right now you can use Google Maps on your phone to add a missing place. This place will be approved (usually within an hour) by an Anonymous account bearing the "G" logo. Now while the POI may not display unless you are actively searching for the place or it's specific category, it will still appear on the map. This makes it even easier to crowd the map with useless information. I am sure it's an insult to those who painstakingly edit the map in MM with accurate information, only to be denied be an LE who knows nothing, and then seeing the useless entries like people's houses and spam get added immediately. What is Google's reasoning behind this?
