Your assessment of Google mobile is totally off as Google Navigation is probably best of breed and it's fueled by Google local. I use it all the time and it's impressive as all hell. Just ask anyone now suffering with Apple maps. As a matter of fact, the Google car (legal to drive itself in several states) is the epitome of just how good Google mobile technology is vs. the competition.
However, that's taking the thread off topic as the topic is the next generation SEO and I think being positioned for mobile and social in a big way is crucial moving forward.
Let's keep it on topic please.
