"Excellent Hard SF"
This book was spectacular. I enjoy hard SF, especially stories that begin in contemporary times, and this book did not let me down. Sawyer does a great job at mixing murder mystery with the skiffy (sci-fi) foundation.
"Excellent"
Mr. Sanderson, turn this into a full novel and I will definitely buy it. The novella was excellent, but far too short.

"A fun, human journey."
Despite the fact the novel is about an AI developing on the web, it is a very human story. Kate's journey was (will continue to be I hope) fascinating, and her character was endearing. I loved it.
