Hi,

First of all, my warm congratulations for this mod, I discovered it today and find it very deep, needed, and I hope PDX will consider to include and/or give a prize for it (I know some people there, they really value this kind of stuff )

As a suggestions, maybe a thing to include and/or develop for the "art" section is the birth and development of photography, it has its own great history and impacts for society (just think to "la carte de visite" or the role it had in developing police methods of controlling people after the Commune).
I could help with that, in the last 14 years I spent my time in the world of photographic culture, I also have experience in programming and I'm italian :)
