Abstract: A facility for managing an electronic document is described. The facility receives from a user input selecting a portion of the document, as well as input designating the selected document portion as being subject to approval-gated sharing. The facility persistently stores an indication that the selected document portion is subject to approval-gated sharing.

Abstract: A facility for managing information about document-related activities is described. In some cases, the facility uses particular kinds of structures to represent, in a document graph, document-related activities performed by particular users. In some cases, the facility uses these structures to enable one user to subscribe to the document-related activities performed by another user. In some cases, the facility uses these structures to aggregate document-related activities performed by users in a group of users, such as by aggregating topics that are addressed by documents that are the subject of these document-related activities. In some cases, the facility uses particular kinds of structures to represent, in a document graph, tasks that certain users either can help with or need help with. In some cases, the facility uses these structures to match users that can help with a task with users that need help with a task.

Abstract: A facility for annotating portions of a document shown in a visual representation of the document with annotations reflecting aggregated document activities performed with respect to the portions is described. The facility specifies a visual representation of at least part of the document. For each of at least two portions of the document that are not identical and that are represented in the specified visual representation, the facility attaches to locations in the document's visual representation corresponding to the portion a visual annotation reflecting an aggregation operation against document activities performed with respect to the portion.

Abstract: A facility for interacting with an electronic document is described. The facility causes to be displayed a visual representation of the document, and receives input representing a painting interaction with a portion of the displayed visual representation of the document that corresponds to a portion of the document. In response to receiving the first input, the facility imposes on the corresponding portion of the document a distinguished content classification level.
