When I installed this plugin I encountered two issues:
1. GoogleCards stopped working correctly. It had previously shown the number of people having me in circles, but that now shows as 0, and my G+ picture is now shown as a broken image icon.
2. Google+ WordPress Widget shows the college I graduated from below my name at the top of the sidebar area occupied by the widget's display. Showing this might make sense to a 20 year old college student, but to a person who is "out in the world" and long out of college this makes little sense. What displays here should be configurable or at least the current display of education institution should be optional
