Google is seriously expanding in and towards the mobile search arena, but after an announcement today by Mark Zuckerberg, the Android architect may be looking at a true game changer. Zuckerberg announced a stable mobile Facebook sign-in and equally direct access to single log-in based services, but what really picks up one’s attention is a new location-based, just about social mobile search service.

“The world has now shifted to where people like my wife stay signed into Facebook 18 hours a day. Now she can see which businesses her friends are using. Soon, we’ll have the ability to even get deals. For instance, the North Face is giving us $1 to check in at a National Park or at one of its stores.”

As blogger Robert Scoble highlighted in his post, this new location-based social FB platform has certain qualities that can easily get a relevant user switch to it, but despite of its somewhat intimidating presence reflected towards Google, Google is Google.  The corporation has been working hard on progressing further into mobile search as well as direct advertising monetizing, all in the light of its own mobile OS, own Smartphone, own huge share of more markets than one can count etc. Direct advertising monetizing will also become available for Microsoft with the growth of Facebook’s mobile social platform, but there’s nothing like a little bit of competition to encourage the development even more ever-attractive offerings to users.
