@jeffjarvis And you can go back further, of course—to Plato, even—and find people concerned about the effect of communication technologies!
I wonder: Pointing to historical concerns about the effects of new communications technologies doesn't prove it's a mere "moral panic" now. Some historical concerns were probably borne out and others weren't. Similarly, some contemporary concerns are likely to prove well-founded, and others won't be.
Or: Lanier might be right even if Erasmus was wrong.
@jeffjarvis (I guess what I'm saying is that ymmv on appeals to historical concerns about communication technologies.)
