I've had HTTP to HTTPS redirects in place for years (originally on the WordPress site) but realised that I'd forgotten to also add www to non-www redirects. That's now sorted. Why is www still a thing in this day and age?
@wearsmanyhats @colinwalker Some hosts won’t let you use the root of your domain, you have to have a subdomain. My static pages are on GitHub Pages, for which I (have to) use the “www” subdomain. I use “blog” on Medium, “micro” on MB, and “letter” on Substack (with a different domain name).
