Those are definitely valid points. The only issue I had was the stark generalization that WA doesn't help or doesn't try to help.
I do agree, though, that these tools are far more valuable and useful to a web professional who DOES have comprehensive understanding of code and and what it is going on under the hood as it allows someone creating complex sites the ability to put in core code scripts super quickly and then the pro user simply has to modify as needed. So what took weeks before now takes a pro user a day or even hours.
But for someone with no understanding of server side concepts, it is a little of a reach to imply that they would be able to get but so far. I am not sure WebAssist, though, is saying that either - at least not deliberately. But, I can see how it may come across that way. But obviously, you hope that people buying this product would have the minimum abilities needed as they were people who purchased Dreamweaver which is, in no means, easy as other Web Development tools.
In other words, the argument would have more validity if WebAssist was, say, developing these tools for a program like iWeb where truly zero experience is needed. But, the fact they are developing them for a professional web design application like Dreamweaver makes me think otherwise.
