This sounds great, but it doesn't seem easy to pull off. Does it sit well with them and are they willing to pay for something like this? EDIT: wording

I would rather get die-hard users who would pay yearly, than constantly have to game the rankings to be high enough to get more sales. Even if the rankings change, you can get longterm value out of those who do pay, even if annual payments make less total customers.
