I'm working on a non-profit search engine (
https://ask.moe) where the plan is to donate 80% of the profits to charities chosen by our users. Google have approved my AdSense account but for some reason then they disable the ads whenever I turn on revenue share (but they're fine with showing ads if I turn it off.. I don't quite understand the logic behind this behavior).
The plan is to provide a general-purpose search engine powered by Google, and then build our own category-specific search engines which will yield much better results thanks to filters.
It's currently written in Vue.js but I'm planning to rewrite it in React/Next.js + TailwindCSS. I would love to team up with people on HN if anybody is interested.
