Google has been preaching about the value of speedy loading times for a few years now. Google offers products like Pagespeed to check the loading time of your pages and also allows you to track loading times with Google Analytics. Unfortunately, the need for speed wasn't part of the programming of the Google Plus One button. Every time you loaded a page with a +One button on it, the button was always one the last items to load. Luckily Google now practises what it preaches.
