Welcome back.
In our previous lesson, we explored the differences between Web1 and Web2. We learned that Web1 was static, offering read-only access to information, whereas Web2 introduced dynamic interactivity—allowing users to both upload and consume content. Essentially, Web2 enabled us to learn from the internet and simultaneously teach it through our contributions.
However, I left out a critical component in that explanation: the Middleman.
Let’s revisit our example using Instagram. Suppose a user, “JK,” uses Instagram to upload and view content. On the surface, it seems like a direct interaction—JK uploads a post and consumes content. But in reality, there’s an intermediary: a server owned by Facebook.
Instead of directly communicating with Instagram, JK’s requests first go through this Facebook server. Whether uploading content or viewing stories and posts, all data passes through this centralized server.
These centralized servers are high-maintenance and require robust security, both in software and hardware. Companies like Facebook take care of these needs:
This infrastructure ensures a seamless user experience. But it begs the question—why does Facebook offer this for free?
The answer lies in data monetization. When users like JK sign up and engage with Instagram, they provide personal information:
This data is aggregated into a profile. Although Instagram is free to use, users "pay" with their data. Facebook can then sell this data to advertisers who, in turn, create highly targeted ads.
For example:
So, while advertisers make money, and Facebook profits from data sales, users are subtly manipulated into spending money—all while believing they’re using a free service.
This model isn't entirely negative. Users benefit from:
But there are serious downsides:
As Web2 expands, so do the limitations and risks of centralized middlemen. The solution lies in creating systems that allow us to:
