I should also add that of my top 10 earners, 7 almost never or never sold at other sites, and vice versa. Which leads to think the best match is hugely manipulated, much more than on DT and SS since the overlap between good sellers is much larger there. This far-off best match plus the fact that recent files (of 2010) sink to the bottom and never sell at all made me stop uploading even before the royalty cut announcement.
I hate to see such speculation regarding Best Match formulas. My mind hurts trying to assign reasons why they do what they do. My experience is that each site caters to different buyers and needs. Some of my best sellers on IS are rarely, if ever, sold at FT. And FT sells only a few of my categories but sells them often. No rhyme or reason. If every site had identical best match formulas I'd wager that my images would sell about the same on every site as they do now.
I'd much rather shoot some more instead of incurring further brain pain.
