I think email newsletters are undervalued. Here are some of my favorites:
- Money Stuff by Matt Levine
A stupendous amount of good content about, well, money stuff. Publishes almost every weekday. (A recent favorite.)
- Gwern by Gwern
Stuff Gwern has been reading in genetics, machine learning, social science, and statistics. Publishes once a month. Amazing & intimidating.
- Benedict Evans by Benedict Evans
Silicon Valley trends by an a16z partner. Always high quality. Publishes once a week.
- Alignment Newsletter by Rohin Shah
Summary of recent developments in AI alignment, curated by Rohin Shah of CHAI, Richard Ngo of DeepMind, and Dan Hendrycks of Berkeley. Publishes weekly.
- Import AI by Jack Clark
Summary of AI updates, a bit more mainstream & capabilities-focused than the Alignment Newsletter. Assembled by Jack Clark of Open AI; publishes weekly.
- Axios China by Bill Bishop
Stories about China, usually on the economy & US-China foreign policy. Publishes once a week. I don't know enough about China to follow many of the stories, but I appreciate the overview. Bishop also writes Sinocism, a daily newsletter also on China.
- Robin Sloan by Robin Sloan
Interesting miscellany by the author of Mr. Penumbra's 24-Hour Bookstore, often about design & new fiction. Publishes every few months.
- Future Perfect by Vox
Vox's Effective Altruism vertical in newsletter form. Publishes weekly. I don't read most of the content, but it's interesting to follow what happens to EA as it passes through the Vox filter.
- Adventures in Typography by Robin Rendle
On typography, publishing, and graphic design. Publishes occasionally.
Also I've heard the Daily Stoic is good, but I'm not subscribed as I prefer my mysticism-infused self-help with an Eastern tinge.
