P.S. You Should Know...
👋 Welcome back to P.S. You Should Know… probably the best newsletter published on Sundays between 6-7am CST, and definitely the best one published by me. Now in its fourth year!

my story 🚀
🎿 We lucked out with 40" of fresh snow in Utah during out trip.

🦠 Late last year, I started compiling everything I know (or think I know) about the human microbiome into a 3,000 word article: Microbiome 2020. After following this field for the last few years, I’m permanently amazed at the enormous impact the tiniest of creatures have on our lives.
Read the article and I bet you’ll be amazed too!

fun facts 🙌
What’s happened to Equifax since the breach? Imagine a business that’s built on selling proprietary data about consumers. Then imagine that business gets hacked and a bunch of that data gets leaked on the internet. You might imagine that customers would leave, consumer lawsuits would erode profits, and the business might be in trouble. You’d be wrong. | learn more
The day big oil was broken. I have mentioned the case of Standard Oil a few times in the past year when the topic of Amazon’s antitrust risks came up. Right after the U.S. government broke Standard Oil into 34 companies, the shareholders (Rockefeller the largest among them) saw their wealth increase dramatically! | learn more
oh, chicago 🏆
Chicago moves to ban styrofoam and single-use plastics. As far as regulations go, I’m rather supportive of this kind. The market has a hard time forcing this sort of change without a push in the right direction. “Starting in 2021, restaurants where patrons eat in would be required to use reusable foodware like bowls and plates.” | learn more
Illinois Senate passes bill to make daylight savings time permanent. It will take an act of the U.S. Congress to make it a reality, but this sounds great! 35 states introduced legislation to do the same last year. [I don’t suggest you click this link because the dumb local news site auto-plays video ads. Boo!] | learn more
tech, startups, internet ⚡
Customer networks are the next big thing for startups. Alex Iskold explains why startups should think about customers as a network rather than as rows in their CRM. | learn more
The aftermath of a $97 million Amazon acquisition. A sober warning for startup employees and investors. “How Eero went from a promising start-up to a company facing mass attrition and debt, and what it says about the hardware market today.” | learn more
better doing 🎯
The lesson to unlearn. A new essay by Paul Graham talks about a lesson we all learn in school that does a poor job preparing us for life. We learn to score well on tests that aren’t actually representative of knowledge. “If tests truly were tests of learning, things wouldn’t be so bad. Getting good grades and learning would converge, just a little late. The problem is that nearly all tests given to students are terribly hackable. Most people who’ve gotten good grades know this, and know it so well they’ve ceased even to question it.” | learn more
Why I never hire brilliant men. This is a story (possibly apocryphal) from 1924. Even a hundred years ago it was clear that ‘fit’ between a business and its people is critical. “Moreover, this is a plodding kind of business, where the money is made by pinching pennies. You’re about as much at home in it as J. P. Morgan would be running a barber shop.” | learn more
Rules to a less complicated life. Lou Holtz, a former football player and coach, uses his humor to give a speech about his philosophy and the simple life rules he uses to live a happy life. | learn more
to your health ⚕
What the 2020s have in store for aging Boomers. “I asked a dozen experts to identify important trends. Some responses were aspirational, reflecting what they’d like to see happen. Some were sobering, reflecting a harsh reality: Our nation isn’t prepared for this vast demographic shift and its far-reaching consequences.” | learn more
under the microscope 🔬
How to swim through goo: lessons from a microbial menagerie. “Swimming at the low Reynolds numbers experienced by bacteria would be like humans swimming through molas­ses. … But motile microbes are unhampered. The fastest bacterium … moves at … a showstopping sixty body lengths per second that puts Phelps to shame (Fig. 1). The ways in which microbes have adapted to life at low Reynolds number are fascinating.” | learn more
thoughts of food 🍔
New Vegan Jewish Deli sells out of food after just 2 days in business. In Chicago’s uptown neighborhood, innovation has arrived! “Sam & Gertie’s will reopen next weekend with a fresh batch of all-vegan, traditional Jewish deli fare.” | learn more
America’s new favorite restaurants are Wawas and 7-Elevens. “Over the past decade, convenience chains have increased sales inside their stores by around 30%, according to the National Association of Convenience Stores, an industry advocacy group. Since 2000, the number of convenience stores in the United States has grown by 28%.” | learn more
on the blockchain ⛓
ETH2 for dummies. “ETH2 is the next generation of Ethereum, and even calling it Ethereum is a bit of a misnomer — it’s an entirely different project, with a new zero-to-one paradigm for how blockchains can operate at scale.” | learn more
