Yahoo! Fire Eagle got a lot of attention when it launched back in March, and for good reason: a cross-platform system for building location data into an application? The buzz died down, though, because there weren't any cool applications using Fire Eagle. That's changing now, though, as the first wave of Fire Eagle stuff rolls out. Metosphere for the iPhone is one of the best of this bunch. Metosphere has several uses. Like any app that takes advantage of Fire Eagle, it can update your location using your GPS or a WiFi hotspot. It also shows you nearby events on Eventful and Upcoming, and nearby Wikipedia pages. There's a map that shows you all of this, plus meetups, emergency alerts, and the best part: messages and geocaches you can create directly from Metosphere. There's no signup required, just use your existing Yahoo! ID.
Geocaching is going to be a big deal very soon, and Metosphere is a great way to play with it on a platform you already know how to use. Show it to your friends and leave each other messages at your favorite hangouts, or start a city-wide scavenger hunt. We'll keep covering new Fire Eagle tools as they advance -- that monthly renewal email is a good reminder to see what developers have been working on.
