Build to Learn vs Build to Earn
TLDR: The best product managers today aren't just facilitating — they're building prototypes to learn fast. In the age of AI tooling, the bottleneck has shifted from delivery to discovery, and that changes everything about what it means to do the job well.

Squash and Stretch: Bringing Disney Animation Principles to Web Interfaces
TLDR: Josh Comeau walks through one of Disney's classic 12 animation principles — squash and stretch — and shows how to apply it to SVG icons and micro-interactions on the web. It's a practical guide that covers both CSS-only and JavaScript-powered approaches, with honest discussion of browser support trade-offs.

A case study of a website adding full mobile responsiveness — with no measurable change in engagement — leads to a model for understanding why motivated users will endure almost anything, and what that means for the realistic limits of conversion optimization.
I Don't Want a Screenshot of Your Claude Conversation
TLDR: Dave Rupert makes a sharp and honest argument about what gets lost when people substitute AI-generated responses for their own thinking in professional conversations. It's not about whether AI is useful — it's about sycophancy, epistemic asymmetry, and what we owe each other as collaborators.

Multi-Agent Coordination Patterns: Five Approaches and When to Use Them

This is the most useful framework I've seen for thinking through agent architecture decisions.

Building Todoist Ramble: How Doist Turned Voice Braindumps into Real-Time Task Capture
TLDR: Doist's engineering and product team built Ramble, a voice-to-task feature in Todoist that processes live audio with Gemini and makes tool calls in real time — no transcription step, no text output from the model, tasks appearing on screen while you're still talking. This is a detailed and honest account of the decisions that made that possible.
