In all fairness, it makes it pretty tough to take your comment seriously when you consistently refer to Rails when you mean Ruby.
Also, I have to disagree. Like the author of the post, I found Olsen's book to be a delightful read. It is certainly not a great "first book" on Ruby, however. I think you ought to read it once you've gained a little better understanding - its wonderful for smoothing out edges and cementing some of the more advanced concepts.
Good point with 'Rails'—my mistake—and I understand that now my competence could be questioned. I meant Ruby of course (which is Rails' core and if you got Ruby well you are a much better Rails dev and I think that's the #1 reason when reading Ruby books => Rails).
I appreciate the author and his work but frankly: I got so frustrated with the style. Go and read chapter 13 and compare all the blog posts about Singleton out there (it's a huge difference). Reading one chapter again and again just to see that someone on StackOverflow drew a far better picture doesn't make you happy. Or take the next chapter 14 about class instance variables: this topic is brought to the reader in a very verbose style and again, the net full of blogs and Q&As deliver better much results. People there even discuss and question the benefit or real-world usage of class instance variables which is fully omitted in the book.

Sorry, I totally disagree, especially the advanced stuff is delivered in better quality in the net. Don't get me wrong but your words sound like the typical not-helpful Amazon reviews (which made me buying this book). BTW, there more annoying parts like squeezing every subject at the end of a chapter in a monotone structure ("Staying out of trouble", "In the wild", etc.) which is getting boring quickly, doesn't give one a better understanding and feels like the author going through his checklist for every chapter.
