There is talk suggesting that the reason Google became a domain registrar is to give them access to the registration details, so I guess they are trying to check on incestuous linking.

Heh, incestuous linking, that's a new one I've heard.

But what you're saying is right, Google has stated over and over that they do not plan on becoming a registrar. So one can only assume that they will be using it for the other obvious reason.

The controversial Matt Cutts has stated that he prefers to have domains located on different c-class IPs.
