I think there has been a lack of interest in smartphone NFC because iOS has no support for it. For example, I have set up a tag to automatically connect friends phones to my WiFi network. You can also stick tags on places to trigger specific actions/mode/app: office, meeting room, car, bedroom. Also one thing that could have been great to share pictures/files/urls with your computer or other phones: Android beam [1]. Sadly Google is removing it.
