Beet,
As my Nederlande colleague, Arjan Gijsbertsen, used to say, "In the Dutch system, if 9 people like hip-hop and one person likes jazz, you play hip-hop 9 out of every ten songs, and one out of every ten songs will be jazz. In the US system, if 9 people like hip-hop and one person likes jazz, you play hip-hop ten out of every ten songs."
Apt metaphor, I think, for proportional representation as opposed to winner-take-all.
Yes, there's a good point to that. The counter-ergument for your system would be that if 10 people are all playing different tunes at the same time, everyone will evenetually get a head-ache...
