Category:High-heeled shoes is an excellent example of the current problem WMF projects are having with creating and disseminating content that is unbiased.
http://commons.wikimedia.org/wiki/Category:High-heeled_shoes
This category is different that most all the other categories about footwear because it contains many images that are not primarily examples of high-heeled shoes. Most other categories about footwear contain mostly images of shoes or the lower leg(s) with a shoe or shoes.
The number of images in Category:High-heeled shoes is higher than most categories about footwear. Approximately one- third of the images are of full body shots of attractive females who are wearing high heeled shoes, and a significant number of them are nude or posed in sexually provocative positions.
There are random women who are wearing shoes and are mixed in with the porn-stars and strip-tease dancers. These women are being objectified and sexualized without their consent because of the way the the images are displayed in the category. See Wikipedia article on Sexualization
http://en.wikipedia.org/wiki/Sexualization for a description of the term.
In each language that has Wikipedia articles about high-heeled shoes, the content is about a type of footwear, so the links in the articles that lead to commons are directing people to nudity or sexual content that they would not anticipate. There are other problems with some of the images, including unclear consent for the image to be uploaded by the subject of the image.
I see this category as a concrete example of systemic bias coming from having a male dominated editing community.
Leather boots is only other category that I found that also has a large number of images of people. It also contain a disproportionate number of images of women who are nude or in sexually provocative poses.
I think that it is important to continue to talk about these issues in the hope that more people with became educated about the problems with with our current methods to collect, categorize, and disseminate content.
