Fire Eagle Launches
Yahoo have launched Fire Eagle (invite only) which promises to revolutionise the geo-web. Yahoo say that Fire Eagle was "designed to help users safely share information about their location with sites, services and people on the Internet."
Essentially you can broadcast your location with any device to Fire Eagle and your geo-data can be made available to any application by Fire Eagle. Here is Tom Coates, one of the developers, introducing Fire Eagle at ETech.
