The concept of "Aggregation Theory" is a powerful framework that explains how certain companies are able to dominate their respective industries by leveraging the power of the internet. According to this theory, the value chain in any consumer market can be divided into three parts: suppliers, distributors, and consumers/users. The key to achieving outsized profits lies in either gaining a horizontal monopoly in one of these parts or integrating two parts to create a vertical solution.

Traditionally, distributors in various industries would integrate backwards into supply, leveraging their exclusive relationships with suppliers to gain a competitive advantage. However, the advent of the internet has disrupted this dynamic. The internet has made distribution of digital goods free, neutralizing the advantage that distributors once had. Additionally, transaction costs have been reduced to zero, allowing distributors to integrate forward with end users/consumers at scale.

This shift in the competitive landscape has elevated the user experience to the most important factor determining success. The best distributors, aggregators, or market-makers are those that provide the best experience, attracting the most consumers/users and suppliers, thus creating a virtuous cycle. This has resulted in a shift in value from previous incumbents, such as newspapers, book publishers, networks, taxi companies, and hoteliers, to aggregators who can leverage modularized suppliers and exclusive relationships with consumers/users.

Two notable examples of companies that have successfully harnessed the power of aggregation are Snapchat and Facebook. Snapchat has modularized attention by integrating individually interesting content with mass-market advertising inventory, providing a new way for brand advertisers to reach a large audience efficiently. Facebook, on the other hand, has built a strong position by making its users its suppliers, giving it exclusive access to user-generated content.

It's important to note that winner-take-all effects are prevalent in these examples. Companies that can effectively serve all consumers/users and continuously improve the user experience have a significant advantage. The digitization of differentiators shifts competition to the user experience, favoring new entrants that are built around the right incentives.

Evan Williams, the co-founder of Blogger, Twitter, and Medium, shared some valuable insights during his talk at the XOXO Festival in 2013. He highlighted that human desires, such as love, money, status, a sense of belonging, influence, answers, and the desire to create, do not change much over time and generations. The convenience of the internet was achieved through speed and cognitive ease, by taking out unnecessary steps.

Williams emphasized the importance of identifying human desires that remain constant and leveraging modern technology to eliminate unnecessary steps in fulfilling those desires. However, he also cautioned against the dangers of prioritizing convenience at the expense of missing the point. He believed that convenience should be aimed at nourishing and freeing people to do better and more meaningful things.

Combining the insights from Aggregation Theory and Evan Williams' talk, we can draw actionable advice for businesses:

1. Prioritize the user experience: In the age of aggregation, the user experience is paramount. Companies should strive to provide the best experience possible, as it attracts both consumers/users and suppliers. Continuously improving the user experience can create a virtuous cycle that leads to long-term success.

2. Identify and cater to enduring human desires: While technology and trends may change, certain human desires remain constant. By understanding these desires and finding innovative ways to fulfill them, businesses can tap into a timeless market and gain a competitive edge.

3. Don't sacrifice meaning for convenience: Convenience should not come at the expense of missing the core purpose or value of a product or service. It should be aimed at nourishing and freeing people to do better and more meaningful things. Strive to strike a balance between convenience and delivering genuine value.

In conclusion, the internet has revolutionized the competitive landscape by enabling companies to aggregate suppliers and consumers/users at scale. The success of companies lies in their ability to provide an exceptional user experience and leverage enduring human desires. By prioritizing the user experience, identifying constant human desires, and avoiding the pitfalls of convenience, businesses can position themselves for long-term success in the age of aggregation.
