I love this plugin. But the problem is that when I visit a post from an outside link, like the homepage, the icons don't show up. If I refresh the page they will be there and be totally awesome. But people that go to the homepage and click "blog," aren't necessarily going to refresh the page.
Go to this link http://schwillyfamilymusicians.com/blog/ and click on "read more" for an article and you will see it doesn't appear. I have it set to float on the left side. Then hit refresh and it will appear.
