Would you consider Slashdot to have "multi-dimensional" voting, given their Interesting, Insightful, Informative, Funny, and (of course) Troll ratings?
It seems to have worked well enough there.

Still, for me at least, I don't find their dimensionality very helpful. "funny" and "informative" are rather broad categories. If all the content on Slashdot could be simultaneously ranked on a scale of "value to startup entrepeneurs looking for seed funding" and "online video content"...that would be useful to me!
I don't have any particular ideas about what should be done, but limiting your choices to "up" and "down" seems so narrow. Maybe I should jsut be happy it works as well as it does!
Slashdot's model follows some theories surprisingly well. The designers really put thought into it.
