Profiles -- Interview with David Wilkins, Mzinga
Introducing a new feature in Learning Solutions! Interviews with innovators in e-Learning. This week: The learning economy is changing, as social software on the Web becomes more widespread and more accepted. Employees are becoming "prosumers" -- producers and consumers of information. As a result, the role of instructional designers could change dramatically. At the same time, demographics are shifting; companies are downsizing, and the need to capture expertise while cutting costs has never been greater. This week's Profile captures David Wilkins' thoughts in this area.
