This is a 1-month old news item (still catching up this summer's valuable geonews to share). Introduced late last year, Yahoo's service for geolocation named Fire Eagle is not out of beta. The best coverage I found is on the GEB and APB. Read their entries to learn more. From the APB entry: "I personally think most people don't understand that Fire Eagle alone does nothing. To use it, you need to hook up apps that determine your location (like those on your phone/laptop/etc. - and pay attention to how they use your location data) and then to apps that you want to use your location data (like for finding local restaurants, etc. - and pay attention to how they use your location data). Yahoo sits in between and brokers the information. I think it's a great way to manage location information and privacy as you can turn off or fuzz up data from the collection side before its passed on the use the data side." See also the Yahoo! Internet Location Platform announced last May.
