This is a decent idea, the fact that everyone votes on posts that are potential money makers is an issue. I myself do it just like you. I could still see savvy individuals looking through for the names of popular bloggers and posters voting for them alone though.
Eventually when the rewards are more distributed I think it would truly show a significant benefit to operate without the dollar values showing for the first payout (I believe there's two payouts now moving forward) at 24 hours.
Makes me wonder should the dollar value be hidden for the next 30 days as well while the post is still in accumulation mode?
