I've long thought about ways to create "Skyrim" websites, by which I mean moddable websites. You can of course do this today with browser extensions (e.g. reddit is almost unusable to me without RES, a browser extension / mod). But that's not good enough UX, that's not gonna lead to "Skyrim" levels of modding.
Could it be possible to make modding part of the app, and let users add / rank mods just the same way they add / rank posts?
When Youtube removed the dislike button I started considering this more seriously. How do you make a Youtube that evolves, can be "forked" like a git repo, a Youtube composed of competing instances / variants (the winner of which is "the default" for users of the app)? Such an app would only need to be created once, and then it would be the ultimate video streaming platform for all time. The default removed the dislike button? Boom, it's not the default anymore.
Some main issues seem to me to be: 1. Predatory mods (hurting/hacking users, or hurting the site), and 2. Inventor incentive (e.g. you made stacker.news, if someone makes a mod that removes all your revenue, why would you still host the site?)
And how to combine such an app with Web5, slashtags, or nostr? Questions questions :)
