Google Plus – How to Remove All Friends at Once

If you go to someone's user page, there's a button "Add to Circles" button, when you mouseover that, it gives you a dropdown to select the circle(s) to add them to. Does your browser have a way to trigger mouseover events?

A few new resources have appeared to try and address this such as ;

... Google+ doesn’t provide any API, so you cannot share directly your circle. This [sharethiscircle.com] wants to be a repository for all those circles, waiting for the day Google will provide a faster way to share your circles.
