Cool, on the basis of that, I don't suck.

FYI, my acceptance ratios are: (The survey results in brackets)
Istock: 82% (71%)
DT: 63% (49%)
SS: 86% (40%)
FL: 83% (not in that survey)
StockXpert: 48% (67%)
Also, I'm quite surprised at the low overall acceptance ratio for SS, That much be quite a burden on the reviewers to chuck out over half of what is submitted... I'd be seriously considering * it in if I were sitting on 40% acceptance personally. Also, I'm a pretty 'average' quality photog. IMHO, or at least the stuff I use for stock is... If I'm sitting on 86% on SS, there must be some really terrible happy-snappers submitting stuff there! (Present company accepted).
My only glitch is StockXpert, but I think that is because I only joined recently and I submitted a whole lot of 'old' stock stuff form when I first joined IS, which would probably be rejected by all of the agencies now, but was above par two years ago. This shows how dramatically the industry is changing. I doubt I'd be able to get any shots from my old Powershot S5 accepted now, noise and artifacting was an issue for that camera even when using raw.. (Why, oh why don't they have raw on the current powershot?)
Interesting...
