I consider these cop-out answers, but Stratechery [0] and Money Stuff [1] are excellent. I'm bewildered daily by Matt Levines ability to write. Mobile Dev Memo is pretty good and follows mainly the mobile ad industry [2].
Apologies for the self-promotion, but in case any tech minded finns are reading this, I write a daily news letter about tech in finnish called Transistori [3].
