And here I was, thinking firefox was screwing up the JS. I guess this should improve the quality of discussions a lot, since a lot of people tend to just skim the few comments at the top. Not displaying the comment scores might make them read more.
That might make sense but it could still mean that a long, pointless, off-topic discussion would rise to the top, above other shorter, succinct comments that might end up buried at the bottom.
I believe the shorter on-topic comment would be voted up more than the off-topic thread (unless ofcourse, the off-topic thread involves a sparky issue like Micheal Arrington).
