Go buy it. :-) Where my book stands out, even today, is in coverage of the practical, big-picture issues of planning, rolling out, and maintaining a wiki in a large, corporate environment. (For example, see Chapter 10, "Practical wiki design.") My team at Vistaprint runs possibly the largest and most successful corporate wiki in the U.S. if not the world. It's 10 years old this Friday and has 250K topics, thousands of users, 100+ custom extensions, and a full-time software development staff since its inception. So we've accumulated a lot of wisdom, and I tried to distill some of it into the book. FYI, my direct report, Daniel Renfro, presented on some of our work and our current challenges at EMWcon last week. DanB
