Are there any academic articles that deal directly with the psychology / sociology of Stack Overflow / Stack Exchange?
I was trying to google this to see if there's any academic talk, but I didn't really see anything. This could certainly be due to my googling skills. I'm looking specifically for Stack Overflow / Stack Exchange and not general social networking or Q & A. I've seen Academic studies and Stack Overflow community, but I'm not really looking for a software engineering perspective (and I don't think they've published anything).
EDIT - just to be clear, I don't want software engineering / business articles (which is what all the articles I have seen are) but psychology / sociology type.
