10 Weekend Reads

The weekend is here! Pour yourself a mug of Danish Blend coffee, grab a seat outside, and get ready for our longer-form weekend reads:
• The Anti-Amazon. One brilliant feature of the Costco experience is, paradoxically, the constraint: as opposed to Amazon, with its near infinite assortment, or even Walmart, which has approximately 130,000 SKUs (stock keeping units, or distinct items) in the average Supercenter, any given Costco will only hold 4,000 SKUs to choose from. While most retailers today assume that consumers want ever greater assortment, Costco’s popularity speaks to a countervailing desire for less choice. Indeed, the pre-selection of items for sale in their warehouses is part of the value proposition: not only are you going to get a lot of a particular thing for a good price, but you also won’t have to deliberate over micro-differences in a more robust assortment. Benjamin Fong on what a genuine alternative to Amazon’s logistics empire would require. A serious, wonky look past the everything-store. (Phenomenal World)
• How do you solve a problem like social media? Part I It’s all well and good saying we should regulate social media. But social media is already regulated. So why is it failing? And what could we do in response? The first installment of a serious policy analysis of what regulation would actually look like—beyond the usual hand-wringing and congressional hearings that go nowhere.

• ‘There Is No Going Back’: The Inside Story of Europe’s Rupture With America: Trump’s tariffs, threats against Greenland spurred a rebellion by top leaders; the limits of ‘flattery diplomacy’.

• The Great Blogging Collapse: What Happened to 100 Successful Blogs? [Study] I tracked 100 once-successful blogs over four years to understand what happened after Google’s Helpful Content Updates and the rise of AI Overviews.

This study reveals the patterns behind the winners, the losers, and what it takes to build a blog that can survive in 2026.(Daniel Stanica)

He joined Lyft’s board in 2021 when the firm was burning cash and losing ground to Uber. Lyft has returned to profitability, with its stock rising more than 75% since Risher took the reins as CEO in 2023. In Q1 2026, the firm had 28.3 million active riders and did $4.9B in gross bookings, with $1.7B revs, and $132.8m in EBITDA. Previously, he held senior roles at Microsoft and Amazon.

Executive Summary

The provided text presents a collection of diverse long-form reads covering topics ranging from consumerism and economics to social media regulation, artificial intelligence, geopolitical shifts, and cultural phenomena. Specific themes include the constraints in the Costco model compared to retailers like Amazon, policy analysis surrounding social media regulation, the nature of the AI boom, historical shifts in international relations concerning Europe and America, patterns in content creation success, cognitive biases influencing decision-making, economic segments like global trucking markets, the psychology of effective altruism, and the reversal of fame trajectories for public figures. The selection suggests an interest in understanding systemic constraints (like assortment limits or regulatory frameworks), the dynamics of rapid change (AI, social media), and the complex interplay between human behavior and large-scale systems.

Full Take

The collection emphasizes a thematic preoccupation with understanding systemic friction and the unintended consequences of massive scale or rapid evolution. The juxtaposition of the Costco constraint versus the Amazon model highlights a tension between infinite choice and curated efficiency, suggesting that value is often derived from limitation rather than excess. Similarly, the focus on AI and social media demonstrates an effort to move beyond surface-level narratives toward underlying mechanics—whether it is the derivative problem in AI or the failure of regulation in social media. The analysis of blog collapse reveals a pattern where algorithmic shifts fundamentally redefine success metrics, suggesting that perceived market success is often ephemeral when underlying content dynamics change. Furthermore, themes like the divergence in international relations and the psychological drivers behind errors in judgment (cognitive biases) connect macro-political shifts to micro-level human failings. This suggests a core inquiry into where control resides: in logistics, policy structures, or inherent human psychology. The implication is that true understanding requires tracing these interconnected pathways rather than isolating discrete events.
