Hi Brent!
Nice example of using rdiscount; however, MultiMarkdown has a batch mode -b that'll do this, as well as a compatibility mode -c if you want strict vanilla markdown parsing.
multimarkdown -b -c *.markdownAdditionally, if you start your md file with:
css: mystyles.cssA full HTML file will be created (rather than a snippet, also done with -f) and the referenced stylesheet used.
(not that writing your own script isn't fun of course! ;)
But since we all love Ruby, here’s a more compact and idiomatic version:

You may want to look at how Jekyll works. It has a simple command that monitors a directory and generates html when a file changes.

Have you thought about using Rake for this? Seems like it would be a natural fit for simplifying this.
