Few extra thoughts (I rushed the last post somewhat because of my time running out in the internet café.)

Thud was far too put-downable for me. Usually I'll have to force myself to put a Discworld book down. This time round it was too easy to do so.

The technomancy... was a a half decent joke for the first reference to Gooseberry, but then Terry overdid it somewhat with his 634 subtle takes on actual product names and the joke became somewhat flat.

As for the following dark... that seemed far too similat to Vimes' struggle with "the Beast". It can rile him up and protect him, but he can control it from going too far. It didn't seem like a new idea, unless Terry was suggesting that the beast was always the following dark. In which case, Vimes is going to be a much reduced character from now on.
