[TiddlyWiki] is a very interesting piece of software. [RoyAshbrook] fist told me about this powerful single page JavaScript, CSS and HTML based Wiki. [TiddlyWiki] is self contained meaning it stores all its code and data without the need of an external system. We have been experimenting with using [TiddlyWiki] as a help system for our Web Applications. It seems like a very easy way to maintain documentation for rapidly changing application. Since [TiddlyWiki] is self contained within a single HTML document it can easily be included within any ASP.NET Application or Service Layer. An application within an application!
