If It's Thursday, This Must Be Listening Post

It's nice to be home, briefly, although it was a shock to fly back into winter. Florida was strange. Orlando is sort of like cyberspace--nothing is quite real and you are never sure exactly where you are. And Miami Beach--where else can you find a Hummer stretch limo? But I've settled back into my routine, building web pages and considering in my spare time such timeless questions as "How would the world look if our eyes could only see the radio spectrum?" or "Why are there no meat-flavored carbonated beverages?" Tomorrow it's off again, this time a train trip to a Minnesota conference. So, next week's Listening Post will go out on Friday, when I return to wherever this is.
