Do social sites with karma need a decay function?
axod: One thing I've thought about in the past is should an upvote/downvote result in a percentage gain/loss instead of absolute.The thing is, if you've only got 3 karma, and someone downvotes you, that's a big deal. But if you've got 3000 karma and someone downvotes you, it's not. Maybe a vote should result in a 1% gain/loss.On the other hand, it probably doesn't matter that much :)
