Keyholes

CHI '08 Extended Abstracts on Human Factors in Computing Systems, 2008
Documents are changing, becoming more malleable. Content operations progress, from command lines to annotation and tagging. Our studies reveal that people in practice share entire documents when portions would suffice. Readers hunt for relevant information. Authors describe laborious processes of selective sharing and redaction.
