I was talking w/ my boss about the potential of data that is injected in twitter, search engines and other social networking websites daily. There is not a consistent API out there that could aggregate such data, map it to a valid location and present that for outside world to use. Trazzler does it in some form, but I can't find an API exposed for use by outsiders and seems to be limited to twitter data only. For instance, Superbowl 2010 will be all over the news and on twitter starting Dec 09/Jan 10. But what does that mean?? Absolutely nothing! Unless somehow you can map that to Miami, FL, USA. Same goes with Oktoberfest (Munich, Germany?). A cool project would be create a database that would update real-time with top search queries, tweets, etc. with a uniform location associated with it along with the ability for user interference to correct any outliers.
