GitHub renders Markdown if you click on a file in the Web repo view.
Or, from the other angle, with Markdown being found in so many places, why aren't there popular viewers for it?
The preview is really only needed if there is advanced formatting or HTML in there. A basic markdown doc should be easy to read in plain text.
And I don't want an extra "preview" pane. That was the specific complaint. Nor do I want these docs in my IDE at all. I want all the available space in my IDE for code.
Again, why have this format all over the place when there are vanishingly few VIEWERS for it? Or vice versa?
