One of the results of the CATaC conference was that I volunteered to help Dr. Leah Macfadyen to refine a wiki she created with relevant literature regarding culture and communication in online environments.
Leah asked me to help, but as it turned out it was already pretty developed and she was ready for it to go live (See Link 2).
Anyway, it is a resource that you can access for some review of literature. I highly recommend you go there for resources regarding culture and communication in online environents.
Feel free to either email comments to me or her.
