I started using Digg Digg when I started my first blog in 2010. Great to use, and easy to install. One thing that I have noticed, and why I did not give this plugin 5 stars. My Pinterest button does not line up properly with the rest of the buttons.
For example, on the post below, it looks like the pin counts go up, but are raised too high in comparison to the other share buttons.
Also, not sure if this could be a future upgrade. Is there a way to show the same buttons above and below the content? If it is not possible coding wise, then not important. Just thought it would be great for bloggers who could use the extra shares.
