Yes - Wikipedia does generate a wonderful debate with regard to its use in education. But few would argue that it is a remarkable resource and at least a good starting point for research.
In this world of media-rich websites, is Wikipedia's primarily text-based content becoming "passé"? A new site - Navify - has taken Wikipedia and attached pictures, videos, and even user comments to selected articles.
BTW - Navify is in beta testing and I is offline today. It was written up in TechCrunch which might explain why it has gone offline - too many requests to handle.
