It's always been easy to share with all your friends on Facebook, but until we introduced Groups last October, there wasn't a simple way to share with just a few people. Much of what we share in our daily lives is only meaningful to smaller groups of people, like our family, roommates, or co-workers. With Groups, you can create a private space to share with just those friends. In the six months since our launch, people have created over 50 million Groups on Facebook.
