I'm surprised by this choice of domains; many of them don't seem to be very appealing for either businesses or individuals. How many people would really want .foo, .boo or .soy?
Given how well .me and .info did (can't remember the last time I saw one of those) I can't see this gaining much traction at all.
Not to discredit Google's attempts here prematurely, but they are known for shutting down non-profitable/low-trafficked services.
...and so on
