👉 Communities' fluidity refers to the dynamic and ever-changing nature of social groups, where members can easily join, leave, or shift their affiliations based on evolving interests, circumstances, or social dynamics. This fluidity allows communities to adapt and grow, fostering inclusivity and diversity by welcoming new members while accommodating the natural ebb and flow of relationships. It reflects the real-world complexity of social interactions, where boundaries are not rigid but flexible, enabling communities to remain vibrant and relevant over time.
