I noticed some images aren’t included in the main ‘sprite’ image. If you’re trying to go for ‘blazing fast’, every HTTP request should count.

A quick test with Google PageSpeed also revealed the CSS has quite a few inefficient CSS selectors.

I’m not trying to downplay your achievements, I wish more people/websites would put the same effort into their site efficiency.

“Move JavaScript to the bottom of all pages”

jQuery was used on getpersonas.com as Javascript-Framework. Usually JS-Frameworks include a ‘domready’ Event, that is fired as soon as the DOM becomes usable. Images don’t have to be loaded for ‘domready’ to be fired.

So far I didn’t tell you anything new, but my question is now, when moving JS to the bottom of the page, wouldn’t all images be loaded before your JS, making domready fire only after the images have loaded?
