Social systems have values - arguments baked into their design. For example, Twitter's core argument seems to be, 'Everything should be public, and messages should find the largest audience possible.' Snapchat's might be, 'Communication should be private and ephemeral.'

In this quote, Robin Sloan is highlighting the inherent values embedded in the design of different social systems or platforms. He suggests that each social media platform carries an underlying argument or guiding principle that shapes how users interact with it. These values are often deeply integrated into the platform’s functionality and user experience, influencing how information is shared and consumed.

For example, Twitter’s core argument is that content should be public and easily accessible, enabling messages to reach the largest audience possible. This value is reflected in the platform’s structure, where tweets are designed to be seen and shared by as many people as possible. In contrast, Snapchat’s core argument is centered on the idea that communication should be private and ephemeral, meaning that messages are temporary and meant for smaller, more personal interactions, which is a direct reflection of its design choices, like disappearing messages.

Sloan’s quote points to the idea that these platforms are not neutral; they inherently carry and amplify specific values that influence the nature of communication within them. Social systems are intentionally created with particular objectives in mind, such as promoting openness or encouraging privacy. The design of these platforms then directs user behavior, shaping how people interact and engage with others online.

Ultimately, the origin of the quote lies in Sloan's observation that social media platforms are not just technological tools, but also vehicles for social and cultural values. The way they are designed communicates implicit messages about how we should behave, communicate, and connect with others, making these values an essential part of the user experience.
