I wrote a similar thing into our project management system here at work. Whenever we receive notifications about a project or something, a little small quote like the ones you're publishing are added to the end of the e-mail...

It would have been nice to add that feature by using your site and grabbing a quote instead of having to find the quotes myself and creating the code (even though it was just roughly an hour).

So maybe make an API for it with one command: "Get". You could return a json object or xml or whatever. {"quote":"blablabla", "author": "Henry the Third"}

It seems like an overkill, though :-)
