"Like" or "Share"

It seems that it would be nice to have a feature to "like" or "share" a project/profile/posting with others.  At the moment, projects are not as successful as they could be, because it is hard for them to go viral.  If you allowed people to like/share a project with their collaborators/familygroup/followers/etc, then things might take off easier.  The only feature that seems to do this now is the relationship finder with famous people. Those show up in the feed and go viral.  But we need a way to do that for projects and perhaps also for other interesting profiles.
