This ground-breaking book is for Twitter fans who want to do more than just answer the question, 'What are you doing?' In the first book about programming with the Twitter API, the barrier to entry for new and casual programmers is lowered with explanation of how each part of the API works and detailed examples of how those parts can be assembled into practical and fun web applications. This book also explains the importance of the Twitter culture and how it has inspired programmers to build their own tools and games. The prerequisite for this book is a basic understanding of how applications are built and hosted on the Web. The PHP and MySQL code necessary to the construction of the example applications will be provided and explained.This work is suitable for IT professionals in small organizations (potential integration for services or products) and Twitter members wishing to learn programming using something familiar (e.g., to detect a specific function that doesn't yet exist). The history chapter will be attractive non-programmers who want to understand the phenomenon.
