I had heard several people say Design for Community by Derek Powazek is a great book and was published well “before it’s time.” As someone who works on several sites that I very much think of as community sites, I picked it up and gave it a read. Published in 2001, the book is just over 13 years old now. Ancient history for a typical tech book. It is a tech book in that it talks about specific websites and specific technologies, and those things do feel ancient (the screenshots are hilarious). But as a design book (and kind of an anthropology book), it has aged quite gracefully.
