• Quickly determine the quality of contributions, and why some are more useful than others
• Become familiar with different models that help you encourage first-class contributions
• Discover tricks of moderation, and how to stamp out the worst contributions in a quick and efficient way
• Engage contributors and reward them in a way that gets them to return

“I like the scope of the book. It provides a lot of new material about a field that is struggling to leap from black art to science, and it provides a lot of useful anecdotal evidence to illustrate the counter-intuitive traps.”

–Douglas Crockford, Senior JavaScript Architect at Yahoo!
