Think of the information - if it was food, would you eat the pig whole unchopped and unchewed?
Think of the download times
Think of the wee 14" screens
Think of the waste of paper
When you're finished remove your brain and study your work with the maximum amount of ignorance you can bring to bear on it.
You should then be able to see some of the holes that the 'what YOU know' was filling in. Knowledge what some other people don't got.

but above all!
Keep It Simple Stupid . . . K.I.S.S.
