The site was registered a month ago. If it ever actually gets and stays popular, see if it has no ads then. The economics of personal interest sites didn't change in the sense that they're any harder to make now compared to the mid-90s. The economics that changed is the Internet now has billions of users and attention being monetized can make you a lot richer now than then. It's very hard for people to see an opportunity to become a multi-millionaire by clicking a button but then not do it because they'd rather maintain a slightly better experience for their audience.

It's, of course, not even loading right now, which gets at the other problem with this "economics" framing. The biggest expense in running an actually popular website isn't creating and publishing the first version. It's paying for the infrastructure to serve a meaningful proportion of the entire world. This is clearly not a static site. It's presumably doing some computation on the server side to draw from all these hundreds of different probability distributions that works well enough for a few dozen simultaneous requests but not thousands. There might even be some kind of perverse anti-economics going on here where thought devoted upfront to efficiency and architecture might have made this far more scalable, but the "publish the first thing that passes a basic sanity check" vibe-slop ethos doesn't usually get you that.
