A few weeks ago I highlighted some videos made by Michael Wesch and his students at Kansas State University. If you haven't seen them, I encourage you to do so.
The great part of the Web, of course, is that it makes all of this conversation public, transparent, open to participation by others, and, dare I say, even possible. Sure, before the Internet and blogs existed, Michael, David, and Gary could have exchanged thoughts about Michael's work via mail or e-mail. But this is more powerful (and much more fun).
