The first sign that I had left my personal Kansas came on the flight from Denver Des Moines. I was trying to sleep at my window seat in the 737. Next to me were two young women talking quietly, as the one in the aisle seat demonstrated a very interesting laptop that appeared to double as a writing tablet. I pretended not to be interested. I'm a lousy eavesdropper, because my hearing always has been useless in noisy places. But I could hardly miss it when the woman with the laptop said, "Doc Searls will be there."
