Abstract: A system for conducting on-line discussion which facilitates said discussion by means of allowing contribution of asynchronous audio-visual segments from at least one class of users, standardizing these segments according to common parameters, linking these segments into smooth streams that are visible by at least one class of user as if they had been generated continuously in a discussion or debater format. The invention includes methods of collecting and standardizing said segments. Embodiments allow for threaded and linked viewer interaction, as well as moderator style control.
