We take as our premise that it is possible and desirable to design systems that support social processes. We describe Loops, a project which takes this approach to supporting computer-mediated communication (CMC) through structural and intemctive properties such as persistence and a minimalist graphical representation of users and their activities that we call a social proxy. We discuss a prototype called Babble that has been used by our group for over a year, and has been deployed to six other groups at the Watson labs for about two months. We describe usage experiences, lessons learned, and next steps.
