[Original Link] From Memex 1.1:

Paul Strassman did a lovely, polemical piece for PBS about the risks implicit in a software monoculture (i.e. a world where everybody uses Microsoft software) in which he used analogies like the Irish potato famine to illustrate the point. Microsoft then replied with a thoughtful piece. Both arguments are flawed, but the exchange is instructive and would make excellent material for class discussion.
