In reply to Mehran Jalali.

It's an interesting overview of the subject of complexity. Potentially good if you know nothing of the area at all, or if you're about to delve heavily into the topic. I'm breezing through it quickly with an eye toward reading his more technical level networks textbook that came out last year.

Some of the pieces so far are relatively overwritten given that it's now more than 15 years later... but the general audience then probably needed the extra back story.
