I think the Slashdot voting system was excellent and loved the multi-dimension approach. In what way did/do you feel it didn't work.

FWIW Steam has a second voting dimension for humour in users game reviews.

Maybee analyse the discussion following with a NN for quality indicators? Long statements, comenting part of the original post and a absence of sarcasm/name calling should allow for a good evaluation of productive posts. Maybee the bot could even Merge uniform opionion posts into a stack, so that ideology biased posts shrink from view and the interesting nuggets show up earlier.

I'm more for KISS and YAGNI.

This sounds too convoluted a process.

We have vote up and vote down buttons. If the people like and upvote a funny (but trivial) comment, in the end it's their prerogative.

Slashdot is still a better community than HN
