> I think it's time Markdown should be supported natively by browsers.

I'd rather have AsciiDoc become the default lightweight documentation format. Markdown suffers from competing standards regarding extensibility beyond basic formating, whereas AsciiDoc is a quite direct translation of the solid standard Docbook.

Extending Markdown to anything more complex than bold, italic or headers requires deciding among a number of competing tools with different syntax and installing them as extensions. AsciiDoc has features as tables, references, images or metadata integrated in the standard, and it has been designed for extensibility, while Markdown was not.

There is an advantage of using Markdown over AsciiDoc, which is that it is currently supported by a larger variety of tools. But that advantage is somewhat negated by its different and slightly incompatible flavors.
