Has anyone made a markdown only web browser? Consumers should be able to control the presentation of the content they view. They should provide the theme. Markdown could provide the minimal content and linking. It seems like it would be possible to remake all the major web properties this way while returning control back to the consumer and preventing egregious advertising, tracking, and popups. Reddit, Google Search, substack/medium/etc all could be remade in this more consumer-centric viewport. The markdown browser would be a strong promise a lot of anti-user behavior. The modern browser is more an application development platform - let's treat it that way. A web browser's presentation should be in control of the consumer.
