It just occurred to me that Microsoft’s OneNote, the application “for capturing, organizing, and collaboratively sharing information”, would work well as a front-end to a Wiki.
For example: A Wiki server could act as repository for publishing shared OneNote pages that in turn can be collaborated on either via the browser (in the true Wiki sense) or within the OneNote application itself.
IMHO, this type of integration would push Wiki’s into corporate environments where knowledge management seems to involve too much post-processing work.
