i just discovered a new site called goodcircle.org . it has a different angle in that you can either create a circle or join an existing one and earn money for your cause through on-line shopping. i will always shop iTunes and Shutterfly now through my goodcircle because a portion of my sale will be directed to my charities ie my good circle. i can also make a direct donation. the site is completely agnostic, so you can start a circle around anything you support. check it out.
