And you know what I have learned by talking to these businesses? It's that WordPress is still not easy enough to use for non techy people.
Nobody wants to touch their website, out of fear of doing something wrong. So they have to go pay someone to do it every time.
I'm running pinkpigeon.co.uk, which tries to actually make websites easy enough to use for everyone. But I am actually running into a problem where people expect all websites to be like WordPress and the first thing you hear is "oh I don't want to learn another thing". It's only when I show them the system, that they go "oh wow, that really is a lot easier". The problem is trying to convince anyone of this remotely via the Internet. Much easier to do in person.
I have the utmost respect for WordPress and used it much myself, but at the moment it's challenging to have to be compared against it when simpler solutions exist.
