[Sigia-l] Lenker book opinions?

[Andrew H Otwell]

A couple people have responded in the last few days to Andrew Dillion's
"Wayfinding" presentation at the IA summit. Matt Jones wrote: ""We talk
about navigating when we mean understanding. This is resonating so
powerfully for me that my teeth are on edge."

This reminds me very much of a book that I've skimmed, but not read: John
Lenker's "Train of Thoughts" (see http://www.trainofthoughts.com/ Flash
required). Lenker's pretty down on IA for overemphasizing navigation and
information heirarchy. Lenker uses a lot of Instructional Design principles
as an alternative approach. That's about as much as I know about it.

Has anyone looked at Lenker's book at length? In this context of "We talk
about navigating when we mean understanding," does it have anything useful
to offer?
