Here's some great weekend reading from John Battelle. He distills and names a pattern that we cover regularly here on The Atlantic: the increasing prevalence of websites that change what you see based on who they think you are.
He calls this the rise of the "Dependent Web." It's a major change to how we've thought about the Internet, and this piece will step you through the (big) implications. Highly recommended:
Here's one major architectural pattern I've noticed: the emergence of two distinct territories across the web landscape. One I'll call the "Dependent Web," the other is its converse: The "Independent Web."
The Dependent Web is dominated by companies that deliver services, content and advertising based on who that service believes you to be: What you see on these sites "depends" on their proprietary model of your identity, including what you've done in the past, what you're doing right now, what "cohorts" you might fall into based on third- or first-party data and algorithms, and any number of other robust signals.
