Thumbs down so far
What works for browsing the surface of the earth doesn't translate well into browsing the night sky, this looks cluttered and messy. Stellarium is far superior and gives a much clear view of what's going on from anywhere on the planet - plus it's easier to use.
A bit too beta for my liking...
