Your honor, I just wanted to build a hierarchy of topic pages.

The Ftrain piece is not so much about that particular lawsuit. It's about the general problem of how, these days, just organizing your own data can lead to unintended legal exposure. Taxonomies are now bound to technologies, and often proprietary.

I like reading Ftrain because the guy is not at all from an engineering culture, and yet he is a self-taught hacker who is turbo-nerdy about the Semantic Web as applied to publishing.
