"The Evaporative Cooling Effect: Navigating Social Software and Building Sustainable Communities"

Introduction:
In the world of social software and online communities, the Evaporative Cooling Effect poses a significant challenge to the long-term success and sustainability of these platforms. This phenomenon, characterized by the gradual decline in the quality of a community as high-value contributors leave, often stems from the ignorance of a fundamental principle: the people who most want to meet others are often the ones who are least desired by the larger community. In this article, we will explore the impact of Evaporative Cooling, the role of social gating, and the importance of scalable social spaces. Additionally, we will analyze the success of Facebook in maintaining quality while scaling its user base.

Understanding the Evaporative Cooling Problem:
The Evaporative Cooling problem occurs when a community experiences a continuous loss of high-value contributors, which gradually reduces the overall quality of the group. As these valuable members depart, the remaining community members may become underwhelmed, leading to a further decline in participation and quality. Eventually, the community reaches a point where individuals with lower skills and awareness dominate, perpetuating a mediocre group.

Social Gating and its Role:
One of the factors contributing to Evaporative Cooling is social gating. Social gating refers to mechanisms that allow participants to self-select out of a group. When unequal roles of participation are introduced, the power gradient shifts, which can counteract the effects of Evaporative Cooling. In smaller communities, social mechanisms can effectively manage social gating. High-value participants receive recognition and reputation from the community, reinforcing their contributions. However, as the community scales, these social mechanisms often break down, leading to a loss of special recognition for high-value members and accelerating Evaporative Cooling.

Scalable Social Spaces: Plazas and Warrens:
To maintain quality while scaling, social spaces need to strike a balance between visibility and scalability. Two fundamental patterns of social organization exist: "plazas" and "warrens." Plazas resemble a central plaza, where every person's interaction is visible to others. On the other hand, warrens consist of smaller, more secluded spaces where interactions are limited to a specific group. Facebook exemplifies a combination of both patterns, with certain features like profiles, friends, and newsfeeds functioning as warrens, while fan pages, groups, and events act as plazas. Twitter, on the other hand, predominantly operates as a warren, except for trending topics, which function as a plaza.

Tradeoffs between Plazas and Warrens:
Both plazas and warrens offer unique advantages and challenges. Plazas are highly visible and facilitate easy understanding of the community. They provide a hive of activity for new users to participate in from day one. However, plazas require a significant initial effort to establish and may face challenges in sustaining engagement over time. Warrens, on the other hand, allow communities to become scale-free, growing without sacrificing quality. However, they can be challenging for new users to navigate, especially when they find themselves in empty warrens with limited connections to hubs of activity.

Actionable Advice for Building Sustainable Communities:

1. Understand the dynamics of Evaporative Cooling: Recognize that the departure of high-value contributors can have a detrimental impact on community quality. Implement strategies to identify and retain these individuals, such as providing recognition and fostering a sense of community ownership.
2. Implement effective social gating mechanisms: Develop mechanisms that allow participants to self-select out of a group while maintaining a balance of power. Consider unequal roles of participation to shift the power gradient and counteract the effects of Evaporative Cooling.
3. Foster a balance between plazas and warrens: Create a social space that incorporates elements of both plazas and warrens. Provide highly visible areas for new users to engage with from the start while also allowing for decentralized, scale-free growth and quality maintenance.

Conclusion:
The Evaporative Cooling Effect poses a challenge to the long-term health and sustainability of online communities. Understanding the dynamics of Evaporative Cooling, implementing effective social gating mechanisms, and finding a balance between plazas and warrens are crucial steps in building and maintaining sustainable communities. By considering these factors, community builders can navigate the complexities of social software and create environments that thrive and evolve over time.
