This is one of those books that I love more every time I reread it. This is my third read and I can appreciate the impressive feats Stephenson pulls off. It's a book that improves as you grow up and can see more of what Stephenson is doing.
I'm almost willing to forgive him the classic Stephensonian ending.

EDIT 4/29/14: This is just to say...I am teaching this book in my "Literature and Networks" seminar and I am super excited! *kermitflail*
