The book will be a developer guide that will help programmers connect existing software to the social web, as well as making brand new social applications. Currently, developers depend on reading the specifications themselves, forum posts, wiki pages, blog posts, and other content spread across the Web. I hope that a single book with practical step-by-step information will make learning about and building with ActivityPub easier.
O’Reilly is the best programming book publisher, hands down. I have a dozen O’Reilly titles on my shelf, all with the famous engraved animal covers, and I use them regularly. I appreciate that the O’Reilly team sees the potential for an ActivityPub book. I have had a great experience with the editors so far.
