I did it. I wrote a word press plugin.
Now, I just need to study up a bit more and
write some database code. I can then create a web service
to parse using another program.

/*
Plugin Name: Only Your YOUR
Plugin URI: http://www.welcometochrisworld.com/THEPOSTFORYOUR
Description: This plugin replaces all occurrences of 'you're' with 'your' and
places a link around 'your' explaining why I would do such a thing...
I was tired of people correcting my use of the word you're.
So, I decided I would never use the word again!"
