How the Spotify Wrapped tech is made and how to save Twitter's backend: Context Collapse #180
Here’s what’s currently on my radar:

As a person who writes books and generally despairs of getting anyone to pay attention to them, I was sympathetic to Armour’s decision to hire a publicist. And also: Armour was a great interview!

Over 43% of digital media subscribers become inactive the day after they subscribe, according to a new report, up from 39% in 2021.
