Fire Eagle, Yahoo's solution for managing how accurately to share one's location, has switched off for good. This news comes from Tom Coates (the Fire Eagle guy) and Gary Gale who also worked at Yahoo for some time. I was a huge fan of Fire Eagle, which launched in 2007. We even did a podcast on it and it's been comvered quite a bit on this blog - either tracking its continued existence or wondering what might take its place.
Fire Eagle was a middleman that allowed users to determine "how much if at all" to fuzz up one's location information for sharing with another app. It was hard to explain and perhaps that's why it never got huge but it was probably ahead of its time.
It also had a really cool name.
