Yes, exactly - it`s not a problem with tool, but with use of it. I also wouldn`t recommend using any software without knowledge how it behaves and what can be done with it.
What you're essentially saying here is that only programmers should have websites. This is not a good attitude. Like saying only mechanics should own cars. We need to change the technology, make it more accessible, not just say that only the technically savvy should use technology.
No, i`ve tried to say that WordPress is simple enough (for a non-technical person after a short training) to deal with the majority of tasks. I don`t know easier open source CMS comparable to WordPress.
