I was hoping they'd go the other way and we could name planets after the rest of Disney's characters... Mickey, Donald, Goofy... Hewie, Dewie and Lewie...
What does it matter really? Pluto hasn't changed.
I don't know what affect Pluto has on horoscopes, but have you thought about the impact us meddling astronomers may have inadvertently had given this decision?
