I have successfully added Facebook Connect to my Commons site (using Drupal for Facebook). I think this would be a useful addition to the Commons Core, but there are probably many more things that need to be thought through--especially Facebook integration of comments. It seems fairly straight forward to use Drupal for Facebook to allow users to share their posts (including comments) on their Facebook page. What seems a little more complex would be bringing comments on posts shared on facebook back into Commons. I'm not a programmer, but I could work on some use cases and try to help in other ways if there are others interested in trying to integrate Drupal for Facebook into an upcoming Commons release.

japerryPlease look at #1558176: Login/signup to Commons site with Google/Facebook account for recent activity on this subject.
Marking as won't fix as this is no longer relevant for newest versions of commons, and versions below 7.x-3.x only receive security fixes. You can also visit #2142923: Upgrading From Drupal 1.5 to 2.x or 3.x for the update status of legacy commons installs and more information on upgrading to the latest version of Commons.
