This is something that is important in real estate. Online real estate is becoming more mobile and location is becoming more important. There are a number of location based startups that have been springing onto the scene. Fire Eagle, a Yahoo location based social networking platform, launched into beta today to store your current physical location in the world and syncs it with other applications. For example, Dopplr, Brightkite and even the new Dash Express can share information with Fire Eagle. Fire Eagle acts as the go-between, storing your location, and sharing it with apps according to rules you set up. This may be the first location aggregator for all of your location-based social applications.
