atila77, your reasoning about downloads is very good! Maybe we need to use those peaks for karma instead of full downloads, indeed. Could you please submit the idea? It seems that we can keep the ratio 100 downloads = 1 karma for these peaks? If v1.0 gets a peak 1000 downloads you get 100 karma points. If v1.1 gets a peak of 1500 you get 150 instead of 100. But if v1.1 gets a peak of only 200 then you get 20 instead of 100. Makes sense.

XFade's point about app karma is also good. We should use it somehow to add karma, but perhaps not to diminish karma. We have talked many times about users diminishing karma by 'being older' if they don't add new karma, to make old disappeared contributors go down the ranking while new contributors very active go up up. It lools that this way would be enough to get minus karma. Just like we do with news, they push your karma up but won't push it down.
