I operate a Wordpress based site so when testing the website on Google pagespeed I recieve a score of 92/100, that is very good I suppose. However, deferring of javascript may be the main concern for growing speed. I already use W3 Total cache to minify scripts.

I'm loading both a Facebook like box, Twitter button and Disqus comments on the website. So my real question is how do you defer the scripts which are loaded from exterior sources?

Please keep in mind that i'm an artist not really a programmer. Any assistance is much appreciated.
