We already have one. I'm describing what Nostr already is. People take seemingly random data (usually, whatever they are thinking about, at the moment), write it down, and throw it into the pool.  Thousands, tens of thousands, hundreds of thousands of people do that every single day.

It all seems noisy, but there are relationships beween the random shitpost and news and countries and food and memes and... Humans aren't always rational, but they're always reasonable. I.e. they aren't random. They always have a reason for what they do or so, even if they aren't aware of it and the reason seems incidental.

Well, all forms of data are like that, but we can't see the reasons. It just looks random or uninteresting. We could just throw it all in and see if we can see the reasons. 

 Got it. Makes sense but isn't it how most social media works? 

 It's how they wish it worked. 😅  

 An obvious one is real estate data. Throw that in the pool. Education data. Monetary data. Pharmaceutical data. Logistics data. Political news data. Literature data. Movie data. Music data...
