Great work!

Jonathan,

You might also have a look at pandoc: http://johnmacfarlane.net/pandoc.
It already supports tables, definition lists, footnotes, superscripts,
subscripts, strikeout, automatic tables of contents, smart punctuation,
etc.  See also:

  - PHP Markdown Extra:  http://michelf.com/projects/php-markdown/extra/
  - Maruku:  http://maruku.rubyforge.org/
  - MultiMarkdown:  http://fletcherpenney.net/MultiMarkdown
  - Asciidoc: http://www.methods.co.nz/asciidoc/

Since you write technical things, you might also appreciate that
pandoc allows you to include TeX math, for example:
$\pi \approx 22/7 = 3.142857$, $\gamma = \frac{1}{\sqrt{1 - v^2/c^2}}$.
In pandoc 0.45, which will be released later today, you'll be able 
to choose from four different methods for rendering TeX math in HTML:

  - approximation using unicode 
  - ASCIIMathML (uses MathML, works only with better browsers)
  - mimeTeX (converts equations to images)
  - gladTeX (converts equations to images)

Pandoc also supports output in formats other than HTML -- LaTeX,
ConTeXt, PDF, RTF, reStructuredText, groff man, S5, and DocBook XML --
and conversion TO markdown from HTML, LaTeX, and reStructuredText.

Best,
John
