networking, or Wi-Fi. In 1999, Apple began putting Wi-Fi interface cards in its iBook
computers, enabling them to wirelessly communicate up to a few hundred feet from a base

also trying to support sustainable community networks throughout the world by developing
and disseminating open-source Wi–Fi software.

want their preferred sites only a click away. The downside of personalization, however, is
that it requires users to fill out a detailed questionnaire that can take up to a half hour to
complete. The questionnaires, users are told, serve to fine-tune their personal pages, but they
also work as market surveys for companies like Yahoo! and Google to decide what kind of
