Abstract: A connection of users to a multi-user virtual space is detected. A multi-user virtual sub-space within the multi-user virtual space is formed. A group of users from among the users are assigned to the multi-user virtual sub-space. Media exchanges are focused for the group of users within the multi-user virtual sub-space by limiting a perception level of media exchanges between users not assigned to the multi-user virtual sub-space relative to users assigned to the multi-user virtual sub-space.

Abstract: A network-based computer system that organizes representations of information provided by users known as Deeds, wherein Deeds represent different versions of the same document, which includes communication such that a Topic may have a plurality of associated Deeds. The system provides any of a plurality of users the ability to create a new Deed by cloning, during which selected data is inherited from an existing Deed. The system provides a plurality of users with the ability to rate Deeds, at any point in time. One Deed associated with a given Topic is considered to be the Current Best. The system makes the Current Best more readily viewable than other Deeds associated with the Topic. The system combines expressions of opinion of a plurality of users to determine the Current Best.
