Although what you mention seems obvious, you have to remember that is quite easy nowadays to cobble up some functionality with minimal knowledge by applying ready-made 'recipes' and following the ton of tutorials available in any language/framework (especially as an experienced programmer). The gotchas become painful when you start to dig through without prior knowledge of the nuts and bolts for debugging/profiling/scaling your application. So I completely agree with you, but I've seen many programmers whip up something in a weekend and not be able to extend the functionality of their app because they had no idea how everything fit together in the 'magical framework' of their choice.
