It looks like the URL won't load without both the p (presumably page?) and s (presumably subscriber?) parameters, and there was no other way to share it.

I wonder what the point is of having a newsletter that doesn't have an indexed web version. It's just a blog, right? Just one that happens to arrive in your inbox as well. What's the downside of listing the entries on the author's homepage as well, making them available to everyone?

I have same feeling for multiple email-newsetters I've encountered over the years

"why is there no blog-like archive?"

it feels like they will be prime example for modern lost media
