"Great action photo! Ok, the face has an unnatural red hue and the crop at the bottom is less than optimum... and the color of the water is not the rich blue one expects from a shot in the pool.. but having said all that, the action, the timing is so compelling that kudos for this shot are certainly in order." - photo critique on PhotoSIG.
I've seen this usage before and smiled then too! 'Kudos' is, of course, singular, and not the plural of 'kudo'. I also thought the quote is a good example of "damning with faint praise".
