As such, they are terrific. I would much rather read a Stealing the Network volume than any hundred HOWTOs and Anarchy Filez: STN has the tone of a really good bullshitting session at a DefCon or Hackers on Planet Earth, hackers spinning war-stories about hacks they've pulled off, or have conceived of. Make no mistake, these are imaginative and brilliant technical people.
As stories, these pieces are sometimes clumsy. The prose rarely rises above journeyman level (it's at its best when the authors stick to declarative, Hemingwayesque sentences, but too often they stray into "colourful" similes and descriptive phrases that can be cliched and even unintentionally funny), and there's not a lot of characterization to be had, and virtually no character development. That said, the book is still a rip-snortin' read, mostly because while it's not the best fiction ever written, it is some of the best, most engaging technical nonfiction you're likely to find.
A couple of the stories are very funny -- I'm particularily fond of the "A Real Gullible" piece, which is an homage to one of the great hacker farces of all time, Real Genius. There's a lot of that kind of nerd humour and nerd folk art sprinkled throughout this volume, and for that alone, it's worth reading.
It's a good formula and a smart one, too: how else could you produce a tech book that was still worth keeping in print 18 months later? Link
