" the simplest tools for producing drop-dead gorgeous Websites".
This here is the dangerous part; thinking that the tool makes the designer. Anyone can produce crap with Flash tools, and all it takes is a stroll through the Web to witness first-hand how much damage Flash can do in the wrong hands.
However I agree that the "designer" will have the last word. And, for as long as Flash allows a graphic designer with no knowledge whatsoever of web practices, standards, and a minimum background in actual computing, to build and "just upload" a website, instead of collaborating with someone who knows what he's doing, we'll be doomed to suffer crap like this.
