Fairpoint
A fair point at a time.
Quick, opinionated tips worth knowing — on Slack, meetings, money, stats, and shipping. Each one's a fair point. Take one, learn the habit, share it with whoever needs it.
Most advice is vague ("communicate better," "use threads more"). Fairpoint is concrete: each one takes a single specific habit, walks you through dozens of real scenarios, and shows you the failure mode behind every wrong answer.
Quick to take — about 5 minutes each — and good to know for good.
