I don't know... it seems no matter what one does, someone will figure out how to abuse the system. All I know is that the current system penalizes the little guy and rewards those who already have plenty. If the little guys were given a fair share, I think there would be more on-boarding of new people. As it currently stands, the small account votes are worth nothing and all those dust votes are collected and given to someone. Getting rid of the 2-cent cut-off would be a good start. At least the small accounts would then have a chance of growing, albeit slowly. The other aspect I would like to see changed is that everyone gets an equivalent share of their curation rewards; those with more HP should not get exponentially more of the pot than the small accounts and voting on popular (large payout) articles should have no relevance to how much of a cut you get. That way, there is no need to vote for the popular articles and one could safely vote for what you really like rather than vote for the biggest returns.
