I'm ignoring it because I'm assuming that you'll download the file ONCE from cdn.awesomesauce.com/oj.js when you're on my website, then the next time you return to my website, or you go to tom, dick or harry's website, once they have the same url for the file and it's cached in your browser, the load time will be near 0.
