This is a cool idea. I would install a Chrome extension that shows a score by every username on this site grading how well their expressed opinions match what subsequently happened in reality, or the accuracy of any specific predictions they've made. Some people's opinions are closer to reality than others and it's not always correlated with upvotes. An extension of this would be to grade people on the accuracy of th…

The problem seems underspecified; what does it mean for a comment to be accurate? It would seem that comments like "the sun will rise tomorrow" would rank highest, but they aren't surprising.

LaunchHN: Announcing Twoday, our new YC backed startup coming out of stealth mode. We’re launching a breakthrough platform that leverages frontier scale artificial intelligence to model, predict, and dynamically orchestrate solar luminance cycles, unlocking the world’s first synthetic second sunrise by Q2 2026. By combining physics informed multimodal models with real time atmospheric optimisation, we’re redefining w…

You joke, but, alas, there is a _real_ company kinda trying to do this. Reflect Orbital[1] wants to set up space mirrors, so you can have daytime at night for your solar panels! (Various issues, like around light pollution and the fact that looking up at the proposed satellites with binoculars could cause eye damage... don't seem to be on their roadmap.) This is one idea that's going to age badly whether or not they…

Yeah, I see this constantly any time Europe is mentioned in a submission. Early European morning/day, regular discussions, but as the European afternoon/evening comes around, you start noticing a lot anti-union sentiment, discussions start to shift into over-regulation, and the typical boring anti-Europe/EU talking points.

“Regular” to who? Pro EU sentiment almost only comes from the EU, which is what you’re observing. Pro-US sentiment is relatively mixed (as is anti-US sentiment) in distribution.
