[Plugin: Follow Button for Jetpack] Does not work with 3.3.2

The plugin displays the Follow button on right bottom of the blog. However, when I try to click it it does not work.

When we click it, I see a JavaScript error in the Chrome console:
“3Uncaught TypeError: Object #<Object> has no method ‘easeOutCubic'”
and in Firefox Console:
“f.easing[i.animatedProperties[this.prop]] is not a function”

I could reproduce this error on your site (https://adityajain.name/) too.

I tried disabling all the plugins except jetpack and this, but still get the same error.

I tested this in Chrome 19.0.1084.52m and Firefox 12.0
