Advanced AI Prompt for Niche Sub-Group (Micro-Community) Scaling

Act as a Social Psychologist and Network Architect. Design a 'Fractal Community Structure' engineered to prevent a massive 50k+ group from collapsing under its own weight and feeling impersonal. Define strict, data-driven parameters for the [SUB_GROUP_CRITERIA] based on hyper-specific interests, skill levels, or geographic regions. Draft the job descriptions for the [LEADERSHIP_ROLES] required to govern each sub-group with total autonomy. Crucially, outline a complex [CROSS_POLLINATION_PLAN] ensuring that the overarching [MAIN_COMMUNITY_THEME] remains the gravitational center, preventing the sub-groups from splintering into entirely separate brands. Anchor the entire strategy in Dunbar's Number to guarantee high-signal, high-trust interactions at the micro level.
