Writing is thinking.
It's not some marginal boring task you can skip. It's the heart of it.

It’s easy to think writing is mainly the transcription of ideas you already have—that is, until you try to write something worthwhile, and you find what you thought were saying transform into something far more interesting in the process. This skips that last step, and that is *not* an improvement.

Pricing externalities is a win for literally everyone! Time to apply this in other cities, and in other parts of New York.
A strange but true finding about NYC congestion pricing:
Drivers’ time savings have overwhelmingly gone to those traveling *outside* the toll zone (i.e., driving from Brooklyn to Queens or within NJ) – not those headed into Manhattan.
Me, in Bloomberg 🧵

Congestion Pricing’s Unexpected Winners: Suburban Drivers
NYC’s controversial toll program hasn’t just sped up trips inside Manhattan, a new paper finds. It’s easing traffic in outer boroughs and neighboring counties.

USPS quietly changed its postmark rules — mail is no longer dated when you drop it off. The “official” date is when it hits automated sorting — sometimes days later
Which could have major implications for mail in voting — it’s a clever way to disenfranchise voters that’s going largely overlooked
