I hesitated to include this one because it is definitely not the typical WordPress blog. But when I was thinking about the best WordPress blogs around, I realized that I check Make WordPress just as often as I do any others out there. You see, make.wordpress.org is the blog where you see what’s going on with WordPress as it happens. You get Gutenberg updates (in their What’s New in Gutenberg? series), team meeting minutes so you can see what was talked about during the latest design team or community building meeting, and that sort of thing. It’s not really a how-to kind of blog, but if you have even a passing interest in the goings-on behind the curtain, Make WordPress Core is going to impress you.
WordPress (WordPress.org) is a free and open-source content management system (CMS) based on PHP and MySQL. Features include a plugin architecture and a template system. It is most associated with blogging but supports other types of web content including more traditional mailing lists and forums, media galleries, and online stores. Used by more than 60 million websites, including 30.6% of the top 10 million websites as of April 2018, WordPress is the most popular website management system in use. WordPress has also been used for other application domains such as pervasive display systems (PDS).
