... in an information-rich world, the wealth of information means a dearth of something else: a scarcity of whatever it is that information consumes. What information consumes is rather obvious: it consumes the attention of its recipients. Hence a wealth of information creates a poverty of attention, and a need to allocate that attention efficiently among the overabundance of information sources that might consume it.

-- Herbert Simon in "Computers, Communications and the Public Interest," 1971

Marais, Hannes and Bharat, Krishna (1997): Supporting Cooperative and Personal Surfing with a Desktop Assistant. In: Robertson, George G. and Schmandt, Chris (eds.) Proceedings of the 10th annual ACM symposium on User interface software and technology October 14 - 17, 1997, Banff, Alberta, Canada. pp. 129-138.

We motivate the use of desktop assistants in the context of web surfing and show how such a tool may be used to support activities in both cooperative and personal surfing. By cooperative surfing we mean surfing by a community of users who choose to cooperatively and asynchronously build up knowledge structures relevant to their group. Specifically, we describe the design of an assistant called Vistabar, which lives on the Windows desktop and operates on the currently active web browser. Vistabar instances working for individual users support the authoring of annotations and shared bookmark hierarchies, and work with profiles of community interests to make findings highly available. Thus, they support a form of community memory. Vistabar also serves as a form of personal memory by indexing pages the user sees to assist in recall. We present rationale for the assistant's design, describe roles it could play to support surfing (including those mentioned above), and suggest efficient implementation strategies where appropriate.
