This Geo-Oriented approach holds a lot of valuable benefits such as optimizing personalized advertisments, change security configs depends on the user's location etc. ,
But this approach cannot get matured as long as privacy is not preserved by the platform - and that's why I recommend to 'hold your horses' and let this innovative idea pass its labor pains..
I think there is an ongoing pattern in Google - they are just keep fitting in to all existing niches, taking only the best elements from each competitor or firm in the niche and adding to the mixture their secret sauce, which will finally make their product the best. Notice that they're conquering (and not slowly..) every niche in the market and I'm sure we haven't seen the latest... Pure Google-Made OS is the destination, and it will be substantially better although it was built upon OSX/Microsoft/Linux elements..
That's how you gain popularity.. upon popular "ancestors".
