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