I think they're riding out whatever seed money came up front.
As I mentioned in another thread, I suspect that their programmer left some months ago since there is no change at all any more at the (features of the) buyer's side of the site. The much requested view counter still isn't there, since they "
concentrate on buyer's features".

Reviews become slower so I figure that Linda keeps the fort alone.
Most of all, I had a thorough look at their "search engine". It apparently works by
upload date, not by relevance or view count. Most recent uploaded come first. Since I uploaded the bulk of my port right when they started, all my shots come very very late in the search results. My DT and SS best sellers for instance come somewhere around page 200. No way I could have sales with such a "search engine", and I'm punished for being an early adopter. I had 3 sales when the site was just up (July, August), then nothing any more, probably since I was pushed back in the searches by later uploaders.
There is also no sign whatsoever on Google of any marketing they would be doing, none. As to SEO, these sites are currently best of feeding individual pictures into Google: mostphotos, cutcaster, zymmetrical, fotolia, scandinavianstockphotos, dreamstime, shutterstock. YAY: none.
Plain Google hits: Istk: 15M, DT: 3.5M, SS: 1.6M, MP: 1M, FP: 550K, ZYM: 520K, CC: 90K, YAY: 77K.
I keep uploading since it's dead easy and I can leech the thumbs of my port very easily so I have a complete overview (they take all).
