Gerry Mckiernan is a Science and Technology Librarian at Iowa State University Library whose writings I insightful and thought-provoking. Given the advent of Web2.0 and the changing paradigm of the web of one from a read-only, centralized source of authority, power and control to that of more of a egalitarian, collaborative “power to the people” sort of thing.
The Grad Center recently decided to experiment using Ning for its alumni network. I think that it’s ease of use and complement of functionality make it the perfect solution to the needs of the GC Alumn. McKiernan’s post references a number of different sites can be used for social networking.
