Step by Step, live walkthroughs of Web applications [icant.co.uk]
Step by step is a YUI-based tool that builds guided walkthroughs of Web applications. This looks like a great tool to build documentation right into a Web application. A context-sensitive help system could be built with this tool. The script is available under a Creative Commons license.
The positives are it is much more interactive than a video or screencast and the users stay right on the Web site.
The negative is that, at least for now, a programmer has to be involved in creating the experience. A screencast or documentation page can be created by a nonprogrammer. However, we could write a front end if someone wanted to use it extensively.
This seems like a great tool for introducing new users to your site. Check out the examples.
