I just think it's neat to be reminded that the generation of original "Hackers", those that find their way through the system by whatever means necessary (the first pages are all about the social aspects of just paying attention to what is around you), is still alive and well. Recommended reading, just to appreciate the mindset that goes into that sort of hacking.
And, because there are people that won't want you to. Acting on it should be illegal, writing and reading about it should not.
