I would like to see a feature on Slashdot, where it would be possible to ignore any/all comments rated "Funny". Ie. while they may get +5 Funny, and as such qualify for showing at the top level when running with "normal" filters, I think the signal-to-noise ratio of non-Funny comments is much better than that of Funny. Or maybe ignoring is not the best way, but sorted last.
There might be better ways to implement this, eg. obviously instead of hard-coding Funny as ignorable, by handpicking the priorities for each rating (others might prefer Funny over Insightful). I'm sure there are other, even more versatile schemes - I'm not suggesting what's the best way to do this, just that it would be somehow possible.
