In general, we found that the freeform nature of text made it possible to adapt Potluck to a wide range of use cases. Any text document, whether it contains prose or a structured personal micro-syntax, can serve as the starting point for an interactive tool. The medium is inherently permissive and flexible. Meanwhile, some properties of Potluck--at least in its current form--limit the kinds of applications that can be built. Text must serve as both the input mechanism for the data and the substrate for designing the user interface, which obviously rules out applications with non-textual data or rich user interfaces and visualizations.
