I wanted dinner recommendations so I scraped 13,000+ London restaurants and accidentally discovered Google Maps is running a shadow economy. Anyway here's a dashboard and a political economy thesis: open.substack.com/pub/laurenle...
How Google Maps quietly allocates survival across London’s restaurants - and how I built a dashboard to see through it
I wanted a dinner recommendation and got a research agenda instead. Using 13000+ restaurants, I rebuild its ratings with machine learning and map how algorithmic visibility actually distributes power.

Good morning, it is 9am here in London. I am confident that the woman who wrote fifty shades of grey was inspired by the London skyline.
However, I am happily on my way to pickup volleyball by tube so I have zero complaints.

pre-writing a devastating obituary for your enemy is god-tier hating of a kind you don’t often see anymore. renaissance haterism. beautiful stuff.
A Sharon Begley byline, almost 5 years after her death.
Upon hearing the news James Watson had died, a STAT reporter said in our Slack, "I wish I could read what Sharon would have written."
Incredible news: Sharon in fact did pre-write a Watson obit. And it is masterful and excoriating.
