I don’t know why isn’t it getting that much attention it’s actually a big deal for people who do vibe coding, for people like who develop micro apps daily. As a teacher it’s so ise to just tell students to go to and practice tables… It’s so amazing

CrowdWis - Ask first, then get routed to relevant people Disclosure: I’m the founder of CrowdWis. Most online communities make you choose a group before you know who is best suited to answer.

At the end you get a debrief which shows what your evals said each quarter and also what was actually true. I lost every run I played myself so far. Every number in the game is source-backed or a labeled design choice. Some of them are wrong somewhere. There is an issue template for challenging a number with a better source, and the better source wins. No accounts, no tracking, no server, works offline after first load. AGPL, nonprofit. Cards and parameters are plain JSON. Contribution is possible without writing code. Would like to have your thoughts if it is fun to play, how you lik
