What are they? What are they about?
Bullets.tech - Research papers summarized to five bullet points
AiWierdness - Janelle Shane exploring crazy, hilarious AI outputs. Very entertaining.
Scott's Cheap Flights - amazingly cheap flight deals, I'm going from Boston to Spain for $300 in a few weeks thanks to this list.
Matt Levine - I've never been interested in finance until I started reading this, he's a great writer.
MIT Technology Review also has a bunch of email lists you should sign up for depending on your interests. And finally, I subscribe to a few different lists for local events and restaurants/bars I like.
