As a daily reddit user for 4+ years, I'd wager that it'll just be an exaggerated amount of the same. With any internet community it seems, given enough time, you get saturated by users 'gaming' it for points/karma/post count/etc. So now the same small number of nothing-else-to-do reddit users trawling the archives for repostable karma material have one more incentive to keep up the high-karma-low-content submissions: money. Sorry for the cynicism.
