not that HN needs more pedantry, but HN’s lightweight markup format is not in any sense a Markdown. I believe that literally the only thing they have in common is that a single set of asterisks yields italics. Bolding, headings, code, lists, quotes, links, etc. don’t transfer from one to the other.
