I personally found the manual addendum really useful. After I had gotten through most of the newby docs that were out there, I picked up the addendum and that was perfect for taking my next steps through the learning curve.

I still think there are plenty of gaps in documentation to work on (most notably missing nation guides and as you mention the spell quick references (I thought there were going to be 2-1 battle, 1 ritual)), but I've always thought the addendum was a real winner in terms of 'good bang for the buck'.
