If I want Finance to contribute, they’re often going to contribute information that people in Finance want to read. Not because they don’t care about anyone else, but because this topic is what they know about and what they can speak on with authority. This being the case, they’re going to want a section of the intranet where they can aggregate Finance-related content.

The editors allegiance (for lack of a better word) is to their department, as it’s the most enduring social structure in an organization. Most departments are physically congruent in a building, so they work with these people every day, and in almost every company I’ve been at, there’s an “us” and “them” mentality.

To get buy-in, you almost have to give them some place in the intranet to call their own. You can draw that content out and repurpose it in other places, but contributors are going to want it to “live” in some place they identify with.
