I would also like to read the stripped down markdown copy and not the original. All the time.
Safari has a very pleasant reader mode that, while not pure markdown, does capture quite a bit of the experience by standardizing presentation and stripping out distractions. You can set Safari to automatically engage reader mode on websites you specify, when it detects an article.
When the GDPR came into force https://npr.org started redirecting to https://text.npr.org with an explanation that sounded like that fact was supposed to annoy you, but I honestly find the latter superior especially now that they’ve added a few more lines of CSS to it.
There was a golden age where lots of websites had WAP (https://en.wikipedia.org/wiki/Wireless_Application_Protocol) versions available while also running their "normal website", and the WAP version was always like 1/100 of the size of the normal website. Still, "normal websites" were minimal compared to now, but when you were on modem, even those websites loaded slow. For some time, most of my browsing were via the WAP versions of the websites I visited during the bi-daily hour of allowed internet access.
Maybe now we'll get something similar, just happens to be for LLMs, but for us who like less bloat, it can be a better viewing/reading alternative. Hope it spreads :)
