What are some of the most valuable newsletters you subscribe to? I'm backing away from social media but will miss the range of links I discover there every day — mostly a mix of political news, contemporary poetry, and stories with quirky, historical angles. I subscribe to 1440 (www.join1440.com), Poem-a-day (https://poets.org/poem-a-day), and political historian Heather Cox Richardson's daily column "Letters from an American" (https://heathercoxrichardson.substack.com/) — all are excellent — but am interested to know what other folks are reading.
