I found the article to be rather superficial, for example; "The original version of Markdown by John Gruber doesn’t specify the syntax unambiguously. For example, it doesn’t have table formatting." Table formatting is an example of a missing feature in a deliberately minimalist specification. Or possibly a feature that is handled elsewhere in the markdown "stack" (by html). So if the syntax is indeed not specified unambiguously (facts not in evidence?) then this isn't a good way of demonstrating that.
