One thing I should point out here: "information architecture" refers to what information goes on what page (a design concept). It doesn't refer to anything such as database schemas or any other programming concepts.
This is interesting - typically I've only come across the term 'information architecture' as it relates to design.
That being said, it's not surprising considering how much leeway for interpretation 'information architecture' has.
This could be subtitled "IA for really simple sites"
