I've tagged an 0.1 version of the book I'm writing: "Learning Go". It currently has 7 chapters. The first five are finished. Chapter 6 and 7 still need work. The exercises can also use some (more) love. The current chapter list of "Learning Go" is:

1. Introduction
2. Basics
3. Functions
4. Packages
5. Beyond the basics
6. Concurrency
7. Communication

To get it:

• PDF download
• Gitweb repository
