There are books. Currently two of them.
Managing Humans was first published in June 2007. This book is published by Apress. While much of the content originated on the weblog, every chapter has been meticulously rewritten and edited. In June 2012, I published the second edition of the the book, which added 14 new chapters and removed several embarrassing chapters.
There’s a promotional website for the book, which you should probably check out.
