For example, the "Software Engineering" namespace is visible to all peer wikis, as is the "SQL" namespace, whereas the "VFP" namespace is of interest only to the Fox wiki. In this way several disparate communities can share common core topics while keeping the overall focus. A greater SignalToNoiseRatio ensues whilst the overall community scales beyond the interests of each focused wiki. -- StevenBlack
