Interesting idea. The site has some kind of algorithm to "score" the "Aesthetic Quality" of a photograph.
This one scored a 92/100 ... the highest of all 50 I entered ...

... but this one scored 7.4/100 ... go figure. I like this one better ...

Maybe subtracting their score from 100 will give more "accurate" results.

"The Mona Lisa"...26.9
"Moonrise Over Hernandez"...40.3
Thomas Kinkade "Candlelight Cottage"...84.2

A friend submitted a pure color field and it scored a 36! They clearly have some work left ...
On a serious note ... I've always wanted an algorithm to rank images by sharpness/focus and wondered whether that was doable.

That's fairly easy, actually. All that is necessary is to evaluate the amount of high-spatial-frequency information present in the image data and calculate a score for the image, then sort accordingly. The only real trick would be separating noise from actual image data, or high-ISO images might score a false positive for focus. You'd probably have to segregate images by ISO (only compare results with other images shot at same ISO setting) for best results.
