Imeem points

Imeem has two kind of services:
1. Free
2. VIP

VIP is advertising free and has some more features I think. It is not free. Imeem is also generating revenues from advertising which obviously more than VIP service.

Now combining above two, they have come up with a brilliant idea (at least that's what I think):

You are offered points for clicking on ads .. and when you have enough points, you are offered 1 month VIP service.

Pretty impressive idea of making users see the VIP benefits and increasing revenues from ads. Loved it! though it's not new
