A Commonplace Book

I have traveled 36 hours to a conference on robotic technology in central Japan. The grand ballroom is Wi-Fi enabled, and the speaker is using the Web for his presentation. Laptops are open, fingers are flying. But the audience is not listening. Most seem to be doing their e-mail, downloading files, surfing the Web or looking for a cartoon to illustrate an upcoming presentation. Every once in a while audience members give the speaker some attention, lowering their laptop screens in a kind of digital curtsy.
