What if Jakob Nielsen had a blog?

Intranet Information Architecture (IA)

Information about departments or divisions was a top-level category in 46% of intranets, and there was a very long tail of additional categories found in a smaller proportion of intranets.

When we started this project, we had hoped to produce a recommended IA for intranets. Although structural diversity ultimately made this an impossible goal, we did identify an IA skeleton that projects can use as a starting point and adapt to their local circumstances.

Many intranets follow several general patterns. Certain types of companies also tend to follow particular trends. For example, manufacturing companies often include a product-related category in their top-level navigation, whereas companies with a focus on intellectual property often present a top-level knowledge management (KM) category.

Long vs. Short Articles as Content Strategy

Typically, people who really need something are the highest-value users because they're more likely to turn into paying customers. That's why I recommended writing articles instead of blog postings.
But the very best content strategy is one that mirrors the users' mixed diet. There's no reason to limit yourself to only one content type. It's possible to have short overviews for the majority of users and to supplement them with in-depth coverage and white papers for those few users who need to know more.

Of course, the two user types are often the same person — the one who's usually in a hurry, but is sometimes in thorough-research mode. In fact, our studies of B2B users show that business users often aren't very familiar with the complex products or services they're buying and need simple overviews to orient themselves before they begin more in-depth research.

High-Cost Usability Sometimes Makes Sense

When it comes to selecting usability methods, there are many parameters to consider, and many different scenarios. That's why both expensive and cheap usability methods make sense under the appropriate circumstances.
