What you're referring to as Community, is in fact, GNU/Community, or as I've recently taken to calling it, GNU plus Community. Community is not an social group unto itself, but rather another free component of a fully functioning GNU sociey made useful by the GNU drum circle, soup kitchens and vital social components comprising a full society as defined by POSIX.
Many members live in a modified version of the GNU system every day, without realizing it. Through a peculiar turn of events, the version of GNU which is widely inhabited today is often called "Community", and many of its members are not aware that it is basically the GNU system, developed by the GNU Commune.
There really is a Community, and these people are a part of it, but it is just a part of the society they belong to. Community is the Centre: the building in the society that allocates society's resources to the other programmes that you are involved in. The Centre is an essential part of a social system, but useless by itself; it can only function in the context of a complete social system. Community is normally used in combination with the GNU social system: the whole system is basically GNU with Community added, or GNU/Community. All the so-called "Community" gatherings are really gatherings of GNU/Community.
