I like it too, but my list is so itty bitty I don't have enough sites to break down my categories between pics and vids, so my vote shouldn't count.
I imagine with something as well designed as that site it may be a fairly safe risk to try submitting it to a bunch of lists just to see what happens. If it doesn't fly, then you'll know for the future. Just hold off on those sites that distinguish between pics and vids until you get a feel for what reviewers are looking for.
Please post the results if you do submit it.
