I don't hate the idea of an inverse "top" it could be fun. What I use the bounty for with Throwback Thursday Competition is a bit laughable really as it's not really a competition because a) the answers get googled within seconds, which is a shame as I had hoped we'd get more nostalgia comments with stories and memories, and b) like you said, nobody zaps anybody at all meaning as a voting system as you highlighted it's pretty useless.

I'm up for trying anything and seeing how it goes, maybe this Thursday I just try it as inverted zaprank and see what happens. (Probably nothing) But it's worth a shot.
