8. (link to BoingBoing)
Going from nine to eight planets will undoubtedly affect both scientific education and the minds of future generations of mankind, which, let me tell you, are simply going to rot.
When we studied science, we had to remember NINE names. Yes, N-I-N-E. Remembering eight names? Pffh. Easy as walking on a giant piece of firm and non-slippery cake.
Armed with that extra memory cell (and all that spare time - just imagine!), I am afraid these young minds will be filled with mischief and with that something my middle school English teacher used to call "hanky-panky".
But I am grateful that Uranus has not been affected by this whole "define a planet" business. Its status, both as a planet and as a joke of sub-astronomical proportions, is safe. For now, at least.
By the way, ever heard of Venkatesh Ketakar? Me neither.
So read up and show this now-forgotten Indian stargazer some respect for accurately calculating Pluto's orbit in 1911.
