Towards a Steampunk without Steam by Amal El-Mohtar.

I submit that the insistence on Victoriana in steampunk is akin to insisting on castles and European dragons in fantasy: limiting, and rather missing the point. It confuses cause and consequence, since it is fantasy that shapes the dragon, not the dragon that shapes the fantasy. I want the cogs and copper to be acknowledged as products, not producers, of steampunk, and to unpack all the possibilities within it.

I do not have enough "yes" or "+1" in the world to express exactly how much truth and awesomeness is in this article.

And the same goes for Stupid Things We Say by Nisi Shawl. Especially this bit:

Because while steampunk’s nonliterary components—fashion, art, music—are some of the most diverse scenes around, steampunk books and stories I was familiar with often seemed nostalgic for an imaginary vanished age of whiteness. Almost without exception they glorified British Victorian imperialism. They did this despite the fact that many of the cultural, scientific, and aesthetic elements steampunk celebrates had been appropriated from nations the British Empire conquered, and the related fact that the machinery steampunk focuses on had primarily been maintained by nonwhites.
