I think Rob is onto to something here. He's collecting the default icon for a whole bunch of sites. Would be amazing to see the collection expand and analyze the data (male/female, non-human/human, face/full body, etc.) As a side note, last month one of my favorite new blogs, Sociological Images, wrote about the default representations in Facebook which appears as a white male for individual users and yellow men and women when they're showing the whole globe.
