I don't disagree with much of what he posted though.
The reality is that the Wordpress CMS editor is garbage. It gives you 1 single WYSIWYG to control an entire page.
Without plugins and custom development, it's a crappy blogging tool that got stretched too far.
I'm a huge fan of using Wordpress for small business sites, one-offs, landing pages, etc.
I just don't find the editor experience is at all pleasant, easy to use, etc.
But, many vendors build their own editor on top of it to solve for this - at that point you have to wonder if using Wordpress as the core framework has the same value.
It's a deep discussion and one we had at work many times before building our own CMS.
I've been using Wordpress for well over a decade now - I have a love hate relationship with it at anytime.
I ended up voting against it for the CMS product, but when hired to build the website for Canada's largest autoshow, I used Wordpress without hesitation.
