Ask HN: Which substacks do you read as soon as it hits your inbox?

I love Letters of Note. Each post features reflection on letters that were sent/written at some point in time, often but not always by notable people. They are whimsical, short, and have introduced me to many interesting facts and rabbit holes.

P.s. My favourite one so far, where among other things, I learned about the infamous and hilarious “please advise” CBS memo surrounding Miles Davis : https://news.lettersofnote.com/p/this-is-my-favorite-memo-ev...

There's one called Technically Food by Larissa Zimberoff, where she talks about food and food technology. I'm not involved in the space anymore, but I used to sell CPG food and it's fun to read about what's happening in that space.

Money Stuff by Matt Levine - he's great at explaining what's going on in the financial industry.

Ridgeline by Craig Mod - Guy walks around Japan and takes beautiful pictures and writes about it.

I choose not to engage in proprietary newletter programs, but do read a lot via RSS. Here are some that I consider insightful and/or interesting, above average quality, have limited or no commercialization/monetization, and have a chance of being interesting to someone else:

OldHouseGuy Blog: https://www.oldhouseguy.com/ Has great taste regarding old buildings

Syonyk/Sevarg/Russell Graves: https://www.sevarg.net/ Some combination of /homesteading/off-grid/tech passion/tech skepticism/

The Long Now Blog - makes me think different things

Early Retirement Now - in depth financial writings regarding saving money more than the common person.

Tynan.com - eclectic person

Hugo Landau: https://www.devever.net/~hl/ - Thoughtful insights on tech and adjacent topics.

Casey Handmer - Crazy dreams about space and carbon

scripting.com - Old guy shouting at clouds, old-school Internet guy building stuff. I just read it for variety.

I've got a few that I read most, if not every time they hit my inbox:

Slow Boring by Matthew Yglesias: https://www.slowboring.com/ - Daily column of moderate/rational takes on politics and government.

ParentData by Emily Oster: https://emilyoster.substack.com/ - She's an economist who writes about parenting by just reading the relevant studies. If you've got kids or are planning to, start with her book Cribsheet.

Jatan's Space by Jatan Mehta: https://blog.jatan.space/ - Pretty high-quality space-related stuff.

Astral Codex Ten by Scott Alexander: https://astralcodexten.substack.com/ - I'm guessing the HN crowd is already largely familiar with Alexander and Slate Star Codex/Astral Codex Ten.

Patent Drop by Nat Rubio-Licht: https://patentdrop.thedailyupside.com/ - A regular look at some interesting patents that have been filed recently.

The Diff [0] and Capital Gains [1][2] by Byrne Hobert are excellent.

If you're interested in in-depth analysis of current events in finance, tech and other related musings.

Capital Gains is more focused on ideas in finance and how to think about them.
