> Sometimes I look that the O'Reilly Head First or Wiley Dummies books and have trouble keeping track of the actual content I'm not sure I'd be inclined to put both series into the same category. Admittedly I haven't looked at the recent Head First publications and I'm not their target audience but from reading some of the theory behind the style on http://headrush.typepad.com/ http://headrush.typepad.com/ (of "Creating Passionate Users" fame) the original motivation was definitely to communicate effectively. But either way, I suspect most non-technical people learn technical things in a very different way to technical people.
