Rich Wiki Editing

While I love the collaborative authoring aspects of Wikis, I've always thought that wiki markup, while nicely concise, acted as a barrier to their uptake in "the real world". Via socialtext, I've come across Wikiwyg, a JavaScript-driven wysiwyg editor for wikis (designed to integrate into existing wiki s). I just tried out the demo, and while double-clicking to reveal in-context editing is a bit counter-intuitive, it works really nicely.
