Ask HN: Passive income ideas for solo developers?
I made an open source search engine that searches her user curated mind maps on the web. Here is the search :<p><a href="https://learn-anything.xyz/" rel="nofollow">https://learn-anything.xyz/</a><p>Since everything is open source and I can't run ads or add any sponsored content, the only way to support it is through Patreon. I think it is a pretty cool idea and solves a big problem of not knowing how how best to start learning a topic or what learning some topic X is.<p>I hope people will find it useful.
