WB: public kiosks

I thank Marc Ringuette and Phil Karn for their comments on public kiosks. They remind me that public kiosks are not a panacea, and that we need to educate others to that awareness. Nevertheless, let us remember the econmonics of the situation. It is expensive to follow people around--more expensive, say, than an illegal tap on a home phone line. By increasing the cost of the suppression of information, one ensures that more information, in the aggregate, is released. We may not be able to provide for any particular individual's privacy, but we can take actions for which we know that we will increase the total amount of privacy (however hard that would be to strictly define).
