The news this week about firing Carol Bartz, Yahoo's CEO, made us go into the Wayback Machine to recall the many good things that Yahoo has created over its life. While there are many that are lining up to take shots at the Yahoos (certainly justified, including this mention of Bartz here), there are still some things worth noting that came out of Yahoo or that were touched by the company.

Have you ever wanted to walk into a building and be automatically checked into Foursquare, without any action on your part? That's the promise of an intriguing DIY project from electronic engineering hobbyist, Casey Halverson. He has come up with a low-cost solution that involves a Nike+ sensor, a $25 breakout board and a Web service called Stumble.to that watches for electronic devices, then automatically checks you into your favorite places via Foursquare and other location-based social networking services.

Yahoo has just released a new application which brings their location-aware platform Fire Eagle to Facebook's social network. The new app called "Friends on Fire" lets you easily share your current location with a set of trusted friends. Fire Eagle users can also share short, Twitter-like posts with each other. These are quick updates and tips tied to your location and displayed on a map within Facebook. In addition, the Fire Eagle team has also introduced a Firefox extension that lets you update your location with just one click.

Yahoo just announced that the close beta period for its location platform Fire Eagle has ended and that the service is now open for everybody. We wrote about Fire Eagle extensively when the beta was first announced. Since then, a number of high-profile services, including Brightkite, Movable Type, Dopplr, and Pownce have implemented Fire Eagle through the numerous APIs Yahoo provides for accessing the service.
