Offering a plain text version of your website may seem like a novel idea nowadays but I remember a time when pretty much every web page had a printer-friendly version with little to no formatting. I suppose printing web pages has become passé, that is unless you're printing a food recipe.

Thanks for putting together this list, it would be nice to add a short summary next to each link.

Honorable mention: https://text.npr.org/

Not technically plaintext (in the MIME type sense), but still very lightweight, especially when compared to other news sites.

In some web apps I code, I just serialize the view-model when the page is called with a ".json" or ".yaml" at the end. It forces you to be strict about not leaking private/complex data into the views and makes power-users' life much easier.

".txt" is also a good idea for content-heavy pages. Maybe ".md" too? I may try.

berkshirehathaway.com is a great text-only site, containing troves of buffett's letters with much wisdom. though the actual text mostly end up in pdf formats.

Interesting. I've implemented naked CSS on my blog, which isn't quite the same:
