[Air-l] development of social codes around a technology

Hello AoIR list, I'm at work on a MA thesis, and I'm searching for some literature on the development of social codes around new technologies, specifically technologies of communication. Particularly I'm looking for some historic context--how did/do things like "phone manners" evolve? How do we learn what's "rude" or "polite"? How did we decide that all caps in email means "yelling"? How localized is the development of these kinds of rules or codes? And are these codes constantly in flux or do they ever stabilize? Any resources or places to look would be most helpful.
