I don't care much whether Pluto is called a planet, though it's nice seeing people actually talk about the Solar System.
But any definition of a planet that excludes Earth and Jupiter is worthless. "Sweeps out its orbit" is a kludgy phrasing to deal with the Neptune:Pluto 3:2 resonance, but no matter how you phrase it, Pluto is still there, crossing Neptune's orbit, and half the planets in the system have associated asteroids.
