The "WAP Deck" represent the idea that people should find their mobile services or "content" from a startpage when the go online on their phone. this make no sense for anyone who know how the internet grew. Google overtook Yahoo when they still believed that the internet should be organized like a directory, like there were a limited "shelf" space. That wasn't true and it wont be true for mobile either.

Admob, one of the largest mobile ad network has a monthly reach of 50 million unique users, that's about the size of one of the largest carriers in the world.

I'm certain that the concept of "Carrier WAP Deck" will not grow in the same pace as the open mobile web....

Congrats to Loopt! :)
