Fire Eagle, Yahoo's new location sharing service, looks fantastic. My playing started when I tweeted asking if anyone had information on the invites. About 30 minutes later, Dan (geodaniel) dropped me an email with an invite and I got started.

Signing in was very easy because it directly integrates with my Yahoo account just like Flickr does.

The short is that Fire Eagle allows people to handle all their location information in one spot. You just type in your address, and you will be mapped.
