When the addthis_button_pinterest button is used, the resulting pin it button is 25 pixels high, which matches the preview image Pin It uses here: http://pinterest.com/about/goodies/
However, if you actually use pinterest's code, the button is 21px high and looks like this: http://assets.pinterest.com/images/PinExt.png
It appears that pinterest have therefore changed the button size to match like/tweet buttons, which makes things display a lot nicer. However, the addthis code hasn't been updated to match.
Can you please update the addthis code to use the latest version from Pinterest so that the button will display more nicely?
