Understanding the Evaporative Cooling Effect and its Impact on Online Communities

Introduction:
In the world of social software and online communities, there is a fundamental principle that is often overlooked - the Evaporative Cooling problem. This issue arises when the people who are most eager to meet others are the ones who struggle to find meaningful connections. This lack of understanding of the Evaporative Cooling effect is at the heart of many failed social software designs. In this article, we will explore the concept of Evaporative Cooling, its impact on online communities, and how it can be addressed to maintain the quality and growth of these communities.

The Evaporative Cooling Effect:
The Evaporative Cooling effect refers to a phenomenon where the departure of high-value contributors from a community leads to a gradual decrease in the overall quality of the group. As each layer of valuable members disappears, the average quality of the community diminishes, ultimately reaching a point where only unskilled individuals remain. This decline in quality discourages new high-value contributors from joining, perpetuating the cycle of mediocrity.

Openness and Social Gating:
One major driver of Evaporative Cooling is the openness of a community. When anyone can join a community, it often attracts individuals who are below the average quality of the group. These newcomers may initially benefit from joining, but over time, their presence can harm the overall health of the community. This is where Social Gating comes into play. Social Gating refers to mechanisms that allow participants to self-select out of a group. By establishing unequal roles of participation, the power gradient can shift, effectively combating the effects of Evaporative Cooling. However, as the community scales, these social mechanisms may break down, leading to further discontent among high-value members and a faster decline in quality.

The Plaza vs. Warren Design:
To better understand how communities can scale while maintaining quality, we can look at the two fundamental social organization patterns: the plaza design and the warren design. In the plaza design, all interactions take place in a central plaza, visible to everyone in the community. On the other hand, the warren design breaks up the space into smaller warrens, where individuals can only see and interact with the warren they are currently in. While plazas grow by expanding their size, warrens grow by adding more warrens. Both designs have their tradeoffs. Plazas are more visible and easier to navigate, but warrens allow for almost perfect scalability without sacrificing quality. The online world tends to lean towards the plaza design, while the real world operates intrinsically as a warren.

Maintaining Quality in Online Communities:
So, how can online communities combat the effects of Evaporative Cooling and maintain their quality as they grow? Here are three actionable pieces of advice:

1. Implement effective onboarding processes: For communities with warren-like structures, it is crucial to have a well-designed onboarding process to help new users connect with hubs of activity. By guiding newcomers and providing opportunities for engagement from the start, communities can avoid the pitfalls of empty warrens.

2. Foster a balance between plazas and warrens: Striking a balance between plazas and warrens can be beneficial for online communities. While plazas offer visibility and a hive of activity, warrens allow for scalability without compromising quality. By incorporating both designs strategically, communities can create an environment that encourages growth while maintaining the integrity of the group.

3. Embrace user control and personalization: Empowering users to control their own experience is key in combating the negative impact of Evaporative Cooling. Platforms like Facebook, where users have control over what they see, exemplify this approach. By allowing users to curate their own content and interactions, online communities can ensure that each individual has a positive and tailored experience.

Conclusion:
Understanding the Evaporative Cooling effect is crucial for the long-term health and success of online communities. By recognizing the impact of openness, implementing social gating mechanisms, and considering the balance between plaza and warren designs, communities can combat the decline in quality that often accompanies growth. Additionally, focusing on effective onboarding processes and user control can further enhance the experience and engagement within these communities. By taking these actionable steps, online communities can thrive and maintain their quality as they continue to grow.
