I am, like a distressing majority of wikipedia content contributors, a young upper-middle, college-educated male.
Here are some things that interest me:
Strange and awesome historical oddities
Collections of Curiosities, in both the early modern and postmodern style.
Cold War/High Modern social inquiry (up to and including atomic war planning) and design (Bakelite!)
Speculation about coming social trends, as well as antiquated visions of the future and "modern society,"
Media theory (mostly German influenced) and media Archaeology (Dead Media, etc.)
radio and the contemporary academic study thereof, particularly regarding the Orson Welles broadcast. No, it was not a psychological warfare test.
'Conditions and constraints of content creation,' be it music, history, or science
Anthropological study of magic (though this is an area I'll admit I need to read more in)
Anthropology of consciousness
Games and Gaming, considered as objects worthy of study (I'm not quite sure if I can use the term "ludologist" entirely seriously yet.)
Grand Strategy and the debate over "4th Generation War"
