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.
