Also spotted on Boagworld.com: WriteMaps Site Map Application.
From the intro blurb:
WriteMaps is a free web-based tool that allows you to create, edit, and share sitemaps online. As a WriteMaps user, you and your team will be able to build and access your sitemaps from anywhere, without having to rely on proprietary desktop apps and static files. To get started, take the tour or sign-up for an account!
I usually use mind mapping software, such as Mindjet MindManager, but I’m quite interested in checking this out.
