Money Stuff by Matt Levine is a gem. You don't need to work in finance to appreciate Matt Levine's insider take on the people and ideas that are in the news.
I doubt it's underrated by anybody reading it but worth mentioning nonetheless: Money Stuff by Matt Levine. Brilliant, hilarious coverage of all things money by a former lawyer and banker.
I've been running https://hackernewsletter.com for almost 10 years. I think most subscribers these days don't actually use or know about Hacker News, which has been an interesting shift.
It's the only one with trends that actually appear to be growing quickly as I think they do a large amount of scraping of discussion forums. They also do an analysis of why it's growing. There's a different one, exploding topics, too which shows google searches that tend to be growing but quite a bit more slowly.
The daily stoic has been incredibly useful in keeping myself on track ever since I discovered it. Other helpful resources: the YouTube channel "Einzelgänger".
We aggregate the top books found in comments and rank them based on how often they are mentioned and the karma of the user. There's a weekly newsletter sent out with that week's book selections.
Evgeny Morozov, who is a great antidote for technological hubris, has organized with others to create a collection of noteworthy information on a variety of subjects but related to a political, activist theme. One need not agree with this work in order to learn from it.
I'll just add a plug for my own newsletter because I like it and it's relevant to some of the HN audience: https://sourcesort.com. It's interviews with open source maintainers and developers. The interviews vary a bit in length and quality but I learned quite a lot from conducting and editing them and I hope they're interesting to some others too. I think there's still a lot of improvement to be done but given the low number of subscribers I think it's underrated :)
(Newsletter goes out once every week or two, usually on a Sunday).
I've also been writing one for a bit over a year now that might be of interest to HN readers: Reading List, which I use for science fiction / fantasy storytelling commentary, reviews, and news: https://andrewliptak.substack.com/
For those interested in mobility (including micro-mobility) and self-driving vehicle technology (from the perspective of a VC), I highly recommend Riley Brennan's "Trucks | Future Of Transportation" weekly newsletter: http://www.tinyletter.com/transportation
Bank Underground is a blog for Bank of England staff to share views that challenge – or support – prevailing policy orthodoxies. The views expressed here are those of the authors, and are not necessarily those of the Bank of England or its policy committees.
Johnn Four Roleplaying Tips - Great if you GM or are simply interested in fantasy. Been 'subscribed' to him since college, just not all through email. https://roleplayingtips.com/
The Growth Equation - Research on athletes & productivity, with links to scientific papers and well-researched articles. Content is top, I've taken more notes from some emails than I have from entire books. https://thegrowtheq.com/articles/
It's probably decently-known with the Hacker News crowd, but I've met few others in the various places that I've worked who have even heard about it, let alone Bruce Schneier himself. It's a great way to learn about new attack vectors and developments in secure computing
https://www.recomendo.com Recomendo gives a weekly brief collection of recommendations and most weeks I find something really interesting in there. For example: this week, they mentioned battery adapters for tools, which is a useful thing I hadn't heard of before.
Webplatformdaily is run by a guy who does a great job curating. I can say it's made me more aware of Web issues and better at my job. If you pitch like 3/month at the patreon you get a weekly newsletter with short editorial content. Def worth it if you work around the Web.
Globalsecurity provides one of the few other NPOV perspectives on global events, aside from financial news.
Still looking for something equivalent in human interest. I currently suspect the constraints of NPOV and minimal selection bias yield an empty set for human interest.
My motivation to starting one was that most programmers focus too much on the technical details ("get better at Python") and too little on the factors related to career growth or money ("how and when do i ask my boss for a raise?").
