I think this just highlights the mess WordPress is in at the moment. Its become in a permanent state of beta testing and is now too confusing for non technical people to use.

None of my clients can use the new site editor and I don't really blame them as I, someone who has been building WP themes for over ten years, find it buggy and frustrating to use.

I understand something needed to be done to give things more functionality which a lot of people wanted from the number of add on editors and themes which third party companys were making. But I think the way its been done has been messy and currently WordPress is not the solution it used to be for most people wanting to manage their own website.
