Since the original thread about FT rank turned into a general discussion about Fotolia I was wondering if it would be possible to create some kind of weekly
anonymous poll for FT rank, to get some kind of a graph/trend line to see how individual earnings correspond to the 7 day rank.
My guess is that the graph will look something like that :

With a bit more variation in the top contributors of course, since we're dealing with the real world here, not a mathematical model.
Would that be technically difficult to do? Users would just post two numbers - 7 day rank and the amount earned in the last week. The graph would be calculated based on the data points.
