While Tumblr has become something of a niche, and I had switched to it some years ago because I tired of the then free hosting provider’s plan to drop the feature, Tumblr is facing some increasing challenges.
So, it’s back to WordPress.
Self-hosting was an option, and I certainly have the hardware and bandwidth to support it, but in my current state, I’m having difficulty troubleshooting (and comprehending) some of the challenges while stepping through something as [trivial? simplistic?] as setting up MySQL, enabling Apache, and PHP on macOS — meh. Never Mind.
