I really don't understand how you decide what to downvote...

I've had a couple posts this week that got way bigger than normal payouts (newsflash votes), and very little conversation or anything...

Then yesterday's post gets more interaction than anything I've posted in months (and most things on trending), is less than half the payouts of those others, and you give it a downvote that removes more than 50% of the payout :-/
