Remember the day when IS had the pickiest reviewers? My current observation is they seem to accept almost anything i submit. They are propably desperate for new material (?)
In the other hand, SS, DT, FT are getting more and more difficult to submit to. I used to have a 90%+ acceptance ratio, but now its more like 50% (I haven't got the courage to check out my numbers...)
This is how the tables turn...
(Bottom line: the sites should accept almost anything that is technically good enough. Let the customers vote with their clicks and buys and weed out the non-selling crap after it has been online for a couple of years. It's getting really frustrating to submit decent images and get them rejected because they are "too similar" oor "limited commercial value" or something else)
