Given people have varying levels of access to knowledge and technology, does greater access mean greater moral obligations?   Should you volunteer for the [Missing Maps project](http://www.missingmaps.org/)? How does this relate to your feelings about your existing moral obligations? Should you volunteer with the [GeoTag-X project]{http://geotagx.org/)? Does ground-based imagery of disasters influence your perceptions of moral obligation?   Could there be difference in thinking as a humanitarian versus as a consumer in how you personally engage with media?
