Hyperlocal + iPhone = $0 Google Adsense

I was surprised to discover, while Googling, that "hyperlocal" (and) "iPhone" called up zero ads. Similar empty result for "hyperlocal" (and) "Android."

In fact, despite its buzzworthiness amongst the geekset, "hyperlocal" itself has almost no Google keyword ads.  There was not even an ad for "Superphone."
