Generally I feel tempted to file this site under fun with phrase generators, with some ML thrown in to make it slightly more interesting than purely random phrase generator toys. But are there really no use cases for automated checks of aesthetic conventions? Sifting through the data dump of a full day of wedding shots maybe? I know I would be tempted to start with a computer generated shortlist. Mate it with face detection so that you can cluster by subset of attendees (each combination of faces captured must be present at least once in the final set) and... well I guess they already use systems like that, it's 2016.
An entirely unrelated idea in the general area of photography, algorithms and human learning that I still miss is this: an option in manual mode that takes a full auto shot right after the manual one, exposing how good or bad the algorithms are vs the operator. Or do some cameras have something like that? Do manufacturers omit it to not expose deficiencies in their algorithms? Do they omit it to not hurt the feelings of customers when they are worse than auto mode?

but says that The background really adds something special. The background is... full black?
And it hates this image (4.7):

and gives it a "good timing" of 35%. The timing is what makes this photograph ;-)
Also, while direct links work, the back button doesn't seem to update the content of the page?
What's your browser? (re: back button problem)
I think it basically looks to see if something is in focus, and you know the "rule of thirds", which it must have learned from custom-cropped photos uploaded to 500px.
one quick question - the page you linked starts with a top picture and then a set, by "the second picture of this fantastic set" did you mean the second picture on the page (gondolier in dark canal with tight ray of light from above) or second in the "set" (guy crossing tracks running with empty rickshaw)

Does the system have a notion of how sure it is of the rating it gives? [Edit: should it say "without a doubt"? There should be some doubt.]
(Also, is it deterministic (same image always get the same rating); it sure appears to be and it's certainly what people expect of a bot, but that's not how humans rate things...)
Uploaded the second picture of this fantastic set by a 1950's photographer from Hong Kong: http://designyoutrust.com/2016/02/hong-kong-in-the-1950s-cap...
Many of them get labeled as #badcolors or #boring, I guess it might be related to the lack of color features...
