The assumption that Wordpress means a client can edit their own site has been very wrong, for many users. Unless the site is built in Microsoft Word (and I've seen that done..) they are going to be using a professional for edits, and hence I refer back to static builders.
That's why we are developing Strattic, which is a static publishing sites for the popular CMSs like WordPress. This way end-users who aren't techy can continue to manage their sites in our secure staging area, and the site is then published live as static. Our company site is running on our platform - the origin site is WordPress: https://strattic.com. I'd love to hear feedback, and we're also looking for beta testers.
