This paper's characterization of tab overload — including the competing pressures to keep versus close tabs, the mismatch between tabs' flat linear structure and users' task-based mental models, and the costs of re-finding closed content — has been widely adopted to motivate new browser and sensemaking interfaces that better support cross-page information tasks, to define and study the broader phenomenon of "browsing clutter", to ground the design of task-centric tab management systems, and to frame usability problems with excessive open tabs across research on information foraging, personal information management, and browser interface design.
