Hmm. We might take this concept further and make it a "wager" of karma with a minimum bet, and you get gains at some rate proportionate to the size of the bet.

But extending it in this way, it would probably also have to have some effect on the front page algorithm for a large bet to ever make sense. Which in turn could lead to a stagnation where elite posters are constantly sinking thousands of karma points into "sure things" and nobody else can compete. Something to think about, in any case.
