Query: Poor writing. Lots of technical inaccuracies.

I read this after reading Da Vinci Code. The writing of Digital Fortress does not have any depth. He is trying to be funny and sometimes "playful" (e.g. conversions with sexual innuendos involving Midge), but they slowed the pace of the story with unnecessary details. May be Dan Brown is writing this book with a screenplay in mind.The "technical" details cannot even fool a high school kid with minimal computer and internet knowledge. For example, A 64-bit pass code does not need to be represented as 64 characters. You need only 8 characters for that!
