>It all seems to suffer a bit from the "Dummies guide" syndrome - it's easy to simplify the first few lessons on a subject, but you pretty soon hit a wall when you reach the parts that actually require a bit of mental legwork.

I know they'll be light reading, easily consumable, and convey information that is simple and considered "mainstream". The wall you speak of likley means you've leveled up your understanding, and now have a better idea of where to go next.
