Based on all the great comments I received about the draft of my MacRuby book <a href="http://macruby.labs.oreilly.com">http://macruby.labs.oreilly.com</a> I decided to rewrite the introduction chapter and move away from the AddressBook example and instead built a hello world GUI app.<br>

<br><br>I just republished the first chapter online <a href="http://macruby.labs.oreilly.com/ch01.html">http://macruby.labs.oreilly.com/ch01.html</a>  and I would really appreciate your help reviewing it and letting me know what you think.<br>

<br>I received quite a few questions about the book content and/or MacRuby questions related to the book. While I don&#39;t mind responding by emails, I figured it would be best if we would do that in public way so I created a new google group for people reviewing the book but also for people learning MacRuby through the book:<br>
