(I know and I'm sorry, but I just couldn't resist.)
John Scalzi and Scott Westerfeld have been battling -- to the entertaiment of all onlookers -- about whether that odd Kuiper belt object Pluto should be considered a "real" planet or not. Scalzi started it all here, and the comments led Westerfeld to reply here. Scalzi posted two quick responses, and then a longer one.
As for me? Well, I like things to be tidy, and I like them to stay the way they've always been, so I'm torn. Pluto is already untidy (what with its bizarre orbit and teensy-tiny size), but it's been a planet my whole life. I guess I want the astronomers to go off and do whatever it is they do -- keep discovering cool stuff and so on -- but never mention the p-word again.
