"Down-votes are like fines. A down vote is brutally negative and should be reserved for blatantly negative posts and spam. Using it on someone’s post that is not brutally objectionable would amount to issuing a fine at a dinner party. Like, what? So that shouldn’t happen. "

no wonder facebook has only a like button (no downvotes)
I think we must have the opportunity in future to vote without revealing our identity... STEALTH VOTING :)
because right now "everybody" is ass-licking ... I thing it would make quality content easier to pop up (or down , for bullshit) if we had such an option... (edit:from the other side I see the negatives also...hmmm)
