Zuckerberg’s Not So Subtle Dig At Google Circles

This is a slightly narrow definition, the visibility of a group should be an attribute.
Dan Gillmor cites a good use-case:
"I'm considering a circle called "insufferable" for people I find personally annoying but whose work I feel obliged to keep track of, in any case."

For example if I would like to share with my colleagues I would much prefer a centrally organized group instead of everyone keeping their own "work circles" up to date (eg when new interns come and go).
Social networking is about connecting with new people, not a virtual front end for people you already know...
For most people I know, it actually does exactly that.
Pretty good point in my opinion. Maybe groups are a better solution for people who want to share with a limited number of friends. It also is much less work since only one person has to set up the group.
People in the group can see who else is in the group. Groups could be curated (need approval to join) or just open to anyone, and moderated (need approval to post) or not depending on the choices made by the group owner.
