The other ranking..

I think you can climb on that scale by posting more discussions and reply. If you join an interest that is rarely discussed and has only 600 members like one movie or something like that you can climb the charts very fast. But if you put all your effort to money making interest you will be one of 25000 people discussing it so it will be harder to earn. However i don't know if you get paid more if you're on top of a small interest or in the middle of very popular interest. Hope i gave you some ideas, have a great day!
