I think this supports the following facts:
- Phone numbers used to be tied to locations, now they are tied to people. We don’t call a place, we call a number becuase we are trying to reach a person.
- Phone numbers (which are now one element of our identity) should not change. When regulation was finally lifted allowing people to hold onto their mobile phone numbers when switching carriers, that was a major step. However, using a service like this which is not dependant on any carrier or physical location, this gives users the greatest flexibility.
- Google likes innovative, simple applications which it can easily integrate into its other platforms.
