At PDC today we announced Microsoft Azure, which is a new Microsoft product that let’s you build applications in the cloud or extend your current applications. Check out Bluehoo which is the first non-Microsoft application using this technology.
Quoting from their Web site, Bluehoo is a mobile app that helps you make new social connections with the people around you - for business or for pleasure. Bluehoo uses Bluetooth to discover "hoos" around you right here, right now, shows you those people’s profiles and helps you start conversations. The Bluehoo Beta mobile phone software can be downloaded right now from m.bluehoo.com.
