ePub is in now, for anyone who wanted it:
https://briefing-service.wholemind.w...rld/paper.epub (swap world for ai, us, finance, sports, soccer, labs, crypto, grants or slow-es-b1). Also new since the thread started: forward newsletters to a private address and the paper gets built from those, and it can go to any inbox now, not only a Kindle. Still free 7 days, no card.
