[Air-l] MySpace readings

I am teaching a Geography of Media class this semester and want to include a discussion of MySpace - can anyone recommend any foundational readings that I might use - the readings do not have to be of a geographical nature - I just need something that discusses MySpace as a social and cultural construct - I'm hoping that there might be a few articles that are just basic required reading for any class discussing MySpace - many thanks James Craine Department of Geography California State University, Northridge APCG Yearbook Editor
