Maybe, once everyone seems to have commented who wants to, publish the list again with the suggested changes listed next to the originals?

Gah. Information architecture gives me vertigo. I would think that "content" could fall under either "archives," as you suggest, if user-centered things like restrictions and interfaces and so on are the bigger concerns; or under "planning" if the issues have more to do with stuff like scalability, taxonomies, formats, and so on.

I'm pretty sure almost everybody knows more about this than me. *g*

Thank you again; this stuff is hard! Hope the new job's going well!
