Google today announced Buzz, which is kind of an uber-mashup of Twitter, Facebook, Four Square and just about any other social network you can think of. Share photos, locations -- whatever -- all in real time. It's built in to gmail (some people are already seeing it live), and also plays a big part in the mobile space (natch).

While at CES we had the privilege to present a number of companies at the Mobile Apps Showdown, a live (and online) competition to find the top apps on any of the major platforms. I was paired with Geodelic (formerly Sherpa), a location-based search program with a little trick up its sleeve. Find out what, after the break.
