[Air-l] online group dynamics

Hello all - I just joined the list a week or so ago; I'm a first year doctoral student at UMass Amherst. I'm working on a project on surveillance technology in which I'm exploring stages of group development in a group blog. It is not an anonymous group, but an extension of a graduate course, so we all know each other and see each other face-to-face as well. I've been seeking literature on small group dynamics online - can anyone point me to anything specific? Maybe in organization/management or some other applied context? At this point, anything that seems remotely close would be a big help! Thanks in advance, steph
