At ETech this morning, Tom Coates announced that the Yahoo’s geolocation service Fire Eagle was leaving their nest, and he began handing out in the invitation codes to the product’s private beta. Fire Eagle, as what we’ve written previously, is a big storehouse for personal location information. It has a very cool feature of revealing the information at various resolutions depending on what the person being located wants to reveal, and to whom. And We think it’s an important new service, to a sort of a geo-counterpart to the upcoming Social Graph API that Google is spearheading.
