Here’s another cool app that’ll either make you salivate or quiver in fear of the Orwellian implications. CitySense is a new downloadable application for your Blackberry (iPhone coming soon) that let’s you find out where the party’s at. How? This is the Orwellian bit. CitySense uses technology from its parent company Macrosense which is able to track billions of bits of data based on cell phones, GPS, WiFi and much more. So by sensing where people are, and then by using Yelp or Google to link to that location, you can find out where’s popular or not. The popular clubs, bars etc appear as a red blotch on the map. What’s more, once you use it long enough, it learns what you like and hooks you up with people like you. Currently, the results are only available in San Francisco.
