Brad Templeton deployed a ruggedized WiFi/VoIP-based phone booth at this year's Burning Man — here are build-notes, photos, maps of call-destinations and so forth.
A considerable number of folks invited to use the phone said they didn't know the phone numbers of any of their friends. Today, many people keep all numbers in their cell phone's address book, and never dial the numbers directly. Many of them called their own voice mails since they knew at least that number, and often exclaimed in amazement at just that. (Alas, many of the voice mails they left themselves will have been somewhat garbled due to the internet traffic issues.)
(Thanks, Brad!)
