Integrating weblog aggregation data with enterprise data

I've been thinking about targets that are far off in the weblog services roadmap. Specifically, how do you make aggregated data integrate with other views of enterprise information? The diagram below illustrates how employee data (HR data) can be leveraged to connect people to various types of interests, publications, etc. on the intranet. This rough, generalized illustration suggests the types of data used to associate people with people, with content, etc. It's a way to leverage people's interests and expertise to create communities of practice around topics, projects, products, customers, etc.

Not sure where else to take this idea. It's meant to suggest how weblog aggregation data fits into the bigger picture of enterprise information architecture, a topic that Lou gives seminars on.
