Support non-profit Watsi.org and get an official Hacker News t-shirt. Teespring.com is a startup that allows people to crowdfund awesome custom apparel with no up-front cost and no risk. Watsi.org enables people to directly fund low-cost, high-impact medical treatments for people in need, as previously reported here. Teespring and Watsi are teaming up for a good cause. For the next five days, contributing just $13 to this campaign on Teespring will get you a Hacker News t-shirt and all proceeds benefit Watsi. The shirts are high-quality screen prints, American Apparel material, choice of black or slate grey, and available in either normal or ladies’ fit. The t-shirts do not have any words on them. However, there’s an interesting discussion on HN: What phrase would you put on an official Hacker News t-shirt?
