I.
The rise of AI product UX.
Beginning in the spring of 2022 — about eighteen months before the rest of the industry noticed — the editors started linking the first working essays on how to design a chat interface that didn't feel like a 2003 help-desk widget. The arc now runs to 140+ editions and includes a working critique of the empty-state pattern, four teardowns of consumer copilots, and a quiet, definitive piece on prompt-input ergonomics that has been cited inside the design orgs at Figma and Linear.
II.
The post-ZIRP operating playbook.
From the rate hikes of mid-2022 forward, the editors tracked how the surviving 2021 cohort actually changed — pricing pages rewritten in three weeks, growth teams cut by a third and rebuilt around sales-assist, board decks rebuilt around contribution margin instead of top-line. Forty-eight editions form a working playbook no consulting firm has matched. The arc is the most-requested body of work in subscriber mail.
III.
The craft of writing for engineers.
A quieter, longer arc — ninety editions over three years — on the specific writing problems engineers face in design docs, incident postmortems, RFCs, and the dreaded all-hands slide deck. Treats prose the way the rest of the catalogue treats code: one idea per paragraph, one verb per sentence, kill your adverbs. The running thread has its own page in the archive and is downloaded as a 38-page PDF by teams at Stripe and Vercel.
IV.
Slow tools for thinking.
The oldest arc, beginning with the very first edition in April 2019: links to notebooks, paper systems, plain-text archives, outliners, and the occasional essay on why you should write fewer notes. Sixty-one editions and counting, and the one the curators quietly consider the spine of the whole publication.
