Dapper offers a simple, accessible approach to web content 'mashup' development. It is a free-to-use, online mashup creation tool that requires only a web browser and no software downloads. This book assumes no prior knowledge of Dapper, yet by the end you will be able to develop complex feature-rich mashups that utilize Dapper alone, or Dapper in conjunction with other mashup technologies like Microsoft Popfly, Yahoo Pipes, and the Google Mashup Editor. "It is, by far, the most thorough tutorial anyone has ever written for Dapper and provides excellent step-by-step guides." -- Jon Aizen, Dapper CTO
