The size of the "Pin it" button (for Pinterest) doesn't match the sizes of the other social buttons. Are you planning to address this in the near future?
if not, we can't incorporate it as it doesn't look good...

The one caveat is that you need your og:image meta tag set on the page to be shared in order for the button to show up.
