The Internet is not a panacea, of course. But neither does it seem to be the instigator of the problems we're seeing with academic dishonesty. By looking away from the technology and toward the culture shaping its use scholars are bound to find some fascinating and extremely challenging questions to grapple with.
The problems are real, of course: students are having more and more trouble making choices about how to use sources, and are less and less inclined to understand that some of the practices they sometimes resort to are considered dishonest and are (or should be) taken seriously (a confusion that faculty seem to share, at least to a certain extent).
In short, the question of whether or not technology makes plagiarism easier doesn't seem to matter. What constitutes responsible scholarship given the changing landscape of information exchange, and how we can help each other engage in the practices that responsible scholars engage in, seems the more critical question, and one that we, as a community of educators and students, are better equipped to address.
