Your TWEET button is way off from the others. It's almost twice as big, both in your demo, and when installed on our site. Can you please fix it? Either the other 3 buttons need to be enlarged, o ryou need to fix the Twitter button.

Thanks for bringing this to our attention. That Tweet button is from Twitter and they must have updated their button today. I'll let our developers know and we'll get it fixed as soon as possible.
