The irony is too fine to get lost here, even though explaining it is a mood killer.
Its funny I also missed it on first reading, which tells me have far this has gone.
The web, internet, www, etc literally was a bunch of markup documents linking to each other. That is what a website was. Its even in the name of its language: Hyper Text Markup Language.
Wouldn't it be funny if browsers started rendering markdown and we got to re-create the original simplicity (and ambiguity) of the web this way.
