Crowdsourcing historical research: an experiment

Yesterday I put on google docs an article draft. The piece is called "Landscape Projections" and it is about the presentation of Australia's environment in historical film. You can see it here:

I am interested to gather people's responses to the piece, and any suggestions they may have for improvement. (I was also curious to see how many people actually read it, and I've been pleasantly surprised on that score).

So, take a look, and let me know what you think.
