How-To pages: Informal systems of expertise sharing.

The How-To has recently emerged as a genre of online content that describes how something is done. This study focuses on computer and electronics hobbyists and their use of How-Tos-how hobbyists use existing knowledge to solve technical challenges, how they document their new knowledge for one another, and how they exchange help and feedback. Our analysis describes How-To knowledge sharing as a fully decentralized expertise-location system in which the How-To functions as both a broadcast of the author's expertise and a personal portfolio.
