Objectives to not take into consideration levels of difficulty and applicability to topics

[philljenkins]

The Abstract explains that:

"This document is for people who make web content (web pages) and web applications. It gives advice on how to make content usable . . . "

but does not explain and seems to avoid the mention of levels of difficulty in types of content and types of applications.

When the author is applying the "8 User Story objectives" and the "8 Design Objectives" what else should be consoidered? If these objectives are to be applied to all and every type type of content (subject), then that needs to be made explicit. If instead, the concept of levels and types of topics and subjects are to be considered, and are in fact another dimension (which I recommend) then that needs to be made explicit.

For example, the following video has 5 different audiences at 5 differnt levels of difficulty when trying to explain "quantum computing". Some or some part of the COGA objectives play a more (and some less) significant role in making the explanation of quantum computing (the web site) more or less usable, understandable, memorable, findable, etc.

In other words, do these objectives apply equally to all types in all 5 levels of explaining? why and why not? Are some objectives more important with some types and levels of content? Any guidance or examples for authors to consider when applying the objectives? For example, does "finable & searchable" (User Story 2 objective) even apply to entry level explanations and websites, or is it more applicable when approaching higher levels of difficulty?
