If you're looking for ways of getting quick communication, maybe texting is the way to go. People can't walk these days without having one hand balancing a smart phone. If that's the way people are going to live, it is the case that something that vibrates in their hand is going to get their attention more quickly than an email.

I think when I first realized that something interesting had happened was probably in 1994. There was a 25th anniversary of the ARPANET celebration and... somebody asked the question, 'Where did email come from?' I remembered that I had done this little program back in 1971. People looked back and nobody could find anything that predated it.
