One Beautiful Game, Three Very Different Bets on Innovation

Max Effgen, October 6, 2026September 29, 2026

The richest football league in the world does not run a startup program. The tier below it does. And an ocean away, a much younger league just built one timed to the biggest stage in the sport. Premier League, EFL, and MLS are all trying to modernize the same game….

Top 5 benefits for Washington State students: Educational Choice for Children Act, one year later

Max Effgen, October 2, 2026

Washington State is the holdout that can still grab $700 million for education. A year ago the Educational Choice for Children Act was a new line in the One Big Beautiful Bill. Today it is permanent federal law. It is IRC §25F, the Federal Scholarship Tax Credit, often called the…

First 30 Days of Weighted Walking

Max Effgen, October 1, 2026September 29, 2026

Disclosure: I am an investor in KILOGEAR. I have been a USATF Level 1 coach since 2017. I have coached youth Cross Country for eleven years. This is a first-month plan, not a catalog. Several vest styles can do the job. Placement of weight matters more than the logo and…

Oura subscription backlash

Max Effgen, September 29, 2026September 23, 2026

Oura just shipped its smallest, most polished ring yet — and quietly layered a new paid add-on on top of the subscription you already owe. The Ring 5 launched in May at $399 (Black/Silver; $499 for other finishes), 40% smaller than the Ring 4, with better sensors and 6–9 days…

The Company McLuhan Kept

Max Effgen, September 27, 2026September 23, 2026

Pierre Teilhard de Chardin, Thomas Aquinas, G. K. Chesterton, T. S. Eliot, James Joyce, and Cambridge New Criticism Marshall McLuhan did not arrive at media theory by accident. It was a long apprenticeship in literature, theology, and close reading. Before he became the man who said the medium is the…

GameChanger: The Operating System of the Saturday Game

Max Effgen, September 24, 2026September 23, 2026

GameChanger started as a way to keep a youth baseball and softball scorebook without a pencil. It is now the default way millions of families watch your favorite 10-year-old’s at-bat from another state, and one of the few consumer apps that can tell you, in public numbers, how large youth…

On-Base Percentage for an Uneven Labor Market

Max Effgen, September 22, 2026September 16, 2026

The useful idea in Moneyball was never that scouts were stupid. It was that the market was paying for the wrong stat. Oakland could not outbid the Yankees for home runs, so Billy Beane paid for on-base percentage — a cheaper way to not make an out. Michael Lewis’s 2003…

How to Do Great Work

Max Effgen, September 17, 2026September 10, 2026

Paul Graham’s important essay from 2023 assumes you can choose your field, your hours, and your risks. Most people can’t. Here’s what still works when you don’t have any of that. Paul Graham is a programmer, essayist, and co-founder of Y Combinator, and the essays he’s published since the early…

MLB’s ABS Challenge System: A Season of Data, Not Robot Umpires

Max Effgen, September 15, 2026September 14, 2026

I grew up with the Chicago Tribune sports section. Box scores before school. Sports Illustrated, This Week in Baseball, the usual stack of player biographies. On television the argument was always the same: the human eye was part of the game, not a defect in it. Instant replay arrived late…

Bo Schembechler jumped the line at an Ann Arbor barbershop

Max Effgen, September 10, 2026September 7, 2026

Over thirty years ago, Bo Schembechler jumped the line at an Ann Arbor barbershop. I’ve told this story before: Ann Arbor, sophomore year, a barber named Jerry who cut hair for Michigan’s best for the right price. Bo — freshly retired from coaching, still UM’s athletic director and President of…
