I'm more interested in what lazyloading plugin you are using for jQuery -- is there an out-of-the-box one that works in Nov 2012, or did you make your own?
Out of the entire article, that's the question? ;) I kid... it's a Wordpress plugin - Lazy Load v0.5. We haven't had any issues with it, would definitely recommend.
(On iPad, it starts to load, then goes to onswipe.com... Black with forever spinning circle)
