If mainstream folk used Delicious and understood what they’re doing when using it, they’d understand themselves to be makers of things on the Internet. The things they make are custom information systems. They make them by writing code, but not in the languages of HTML or JavaScript. Instead they use tag vocabularies that produce and consume web services. And services, I argue, are the most fundamental of the web’s basic building blocks.
