Balloonosphere

This is wierd. I was just checking out my blog statistics and found out that someone from Johns Hopkins University came here while Googling for the term "balloonosphere." As far as I know, I invented that word to describe a horrible peril facing humanity, more dangerous than transfats, Karl Rove, and reality teevee combined. This blog is the only place on the internet where it appears. I wonder what they were looking for.
