I've been dealing with issues for the past few weeks since switching to digg digg with Pinterest not showing pin counts when the pin it button is used more then once on a page/post/loop.
For example the last post on each page of the post loop will show counts but none of the others: http://wholelifestylenutrition.com/
Another example is on a post. The top Pinterest button shows no counts: http://cloud.tunas.co/image/2p3f2w2Z1v2Q but the bottom button does show the count: http://cloud.tunas.co/image/0r32150G1V0c. example url: http://wholelifestylenutrition.com/recipes/the-best-healthy-banana-nut-muffins-recipe-sugar-free-grain-free-gluten-free/
