I stand by my opinion that audiobooks, especially autobiographical/memoir types, should be read by the authors whenever possible — I'm sure the print book is fun too, but I just can't imagine how it could possibly compare to this glorious audio version. 

Sure, you get to actually see the pictures, but we get to listen to the hilarity of Dan and Phil trying to describe them in words. And bickering over sound effects. Did I mention it's hilarious?

Not having been super engaged in the Phandom, a handful of references and inside jokes flew over my head (though they do explain the majority, which could make this book enjoyable even for non-fans). And I imagine that's something hardcore Phans will enjoy, knowing the whole background story/context without having to have it explained, so it's not objectively a bad thing.
