I wasn't bewildered as much as I was want to shoot something. Thought of something yesterday, but it was after I lit the cigar.
I think these things take a bit of time to get rolling, but I do like the single image submission as I believe it forces you to think about what you want to shoot and self-edit, which is a very valuable skill to have. Being able to enter multiples is a bit like "spray and pray" shooting. Sometimes you wind up with 2 great shots and have to force yourself to choose (hint: it doesn't matter, you'll always pick the wrong one), other times you can got a week not finding anything to shoot, like this week. Either way, it's good for you.
