I love well constructed April Fool's Jokes.
I'd like to think that today's Gmail Tap feature was actually born at the Marconi Conference Center in Marshall, Northern California. Been there a couple of times on retreats and always felt inspired by the sheer history of the place. It was part of the Marconi telegraph network - in this case linking the US with the Pacific. All those messages were sent in Morse Code. If you want to hear about why Morse was so important, then have a listen to a programme I made in Scheveningen Radio in the days when Morse Code was still important for maritime communications. The programme about Kootwijk Radio also comes to mind. In both cases, Morse Code was a lifeline rather than a good joke.
