    What Happens When Digital Advertising Collapses?

    📬 Note from the Publisher

    The Attention Economy Is a Lemon. Here’s Why We’re Not Selling It.
    By Peter Cellino | July 2025

    Tim Hwang’s Subprime Attention Crisis is not your typical “tech is scary” beach read. It’s more like an economic crime thriller set inside a Google server farm. His central claim is simple and devastating: the digital advertising industry—the engine that underwrites most of the modern internet—is built on garbage data, fake impressions, click fraud, and the fantasy that targeting is effective. The result? An attention marketplace that looks a lot like the mortgage market circa 2007: bloated, broken, and primed to crash.

    If you run a media company that relies on programmatic ads, this book is a funeral bell. If you run Mercury Local, it’s confirmation you bet the farm on the right thing.

    We built Charlotte Mercury, Strolling Ballantyne, and The Farmington Mercury on the belief that the real value of journalism comes from depth, privacy, and actual human trust—not CPM arbitrage or shady retargeting. That’s why:

    • We don’t run Google Ads.
    • We don’t track your clicks or follow you across the web.
    • Our advertisers are real businesses in your ZIP code.
    • And our revenue model is simple: be useful, be honest, and never sell out your audience.

    We aren’t trying to sell your attention. We’re trying to earn it.

    🛒 If you want to read Subprime Attention Crisis;💡It would be even better if you bought it from your local independent bookseller—assuming you’re lucky enough to have one still. There are too few of them, and we need more bookstores, not more UX designers at Facebook.

    The adtech crash is coming. We’ll be here when it does. And we won’t sell you out for an extra tenth of a clickthrough rate.

    Understanding Web Cookies and Why Mercury Local Avoids Them

    Friction Everywhere—Except Here

    Every hour I hop between half a dozen news sites—and each one makes me agree to cookies before I see a headline. At Mercury Local, you land on the story instantly. No nagging banner, no delay. That seamless first click isn’t luck; it reflects our belief that your time and privacy matter more than another tracker.

    What Is a Cookie?

    A cookie is a tiny text file your browser stores when a site asks. It holds an identifier so the site “remembers” you. Session cookies die when you close the tab. Persistent cookies stick around until they expire or you clear them.

    Why Sites Lean on Cookies

    • Basic Functionality: Stay logged in, save your shopping cart.
    • Preferences & Performance: Recall your language or layout choice.
    • Analytics & Advertising: Track which pages you visit—and show you ads elsewhere.

    The Privacy Trade-Off

    News sites pack in more trackers than most websites—averaging 19 third-party trackers versus eight on non-news sites . First-party cookies come from the site you’re on; third-party cookies come from ad networks embedded everywhere. Those follow-you-around crumbs fuel profiling, price tweaks and, sometimes, data leaks.

    How Server Logs Save Privacy and Deliver Insight

    We use server logs instead of cookie-based analytics. Logs record page requests, timestamps, and anonymized IP ranges—no cross-site profiles, no stranger breadcrumbs. This approach counts real visits without introducing sampling biases.

    Common Objections, Addressed

    “Won’t I see the banner every time?” Yes, unless you bookmark our consent-free URL.
    “Don’t you hurt ad partners?” Not at all—our opt-in newsletters outperform stale ad-tracker campaigns, and local shops love the clarity.

    What You Gain—and What You Trade

    You gain faster pages and no hidden tracking. You trade automatic preference storage—you might log in more often. We think that swap is fair: you stay in control.

    Take Control Everywhere

    Clear cookies in your browser’s privacy settings. Flip on “Do Not Track.” Install a privacy extension. Or just visit a publisher that skips the stalk-and-sell model entirely.

    Conclusion & Strong Invite

    Cookies aren’t inherently evil—they can power good features. But they’re too often abused. Next time a banner blocks your view, know what’s at stake. Tell us about your worst cookie-banner nightmare in our one-question survey.
