I’m not suggesting you send your users to my prototype! The prototype is only that, a prototype, not a product. But the product is coming. (Soon™️!) So if I were you or any dev who hasn’t been following this closely and doesn’t want to experiment with alpha (or pre-alpha) stuff, I’d wait until there’s at least one stable, user-facing WoT service provider who supports NIP-85, and when it’s ready (easy for users to sign up, good UX, all open sourced, etc), I’d be ready to integrate scores using this method.

Yes, I created GrapeRank. I have articles explaining what it is and how it works. My prototype is open source and the rebuild will also be open source, which means you can be your own WoT service provider. And our #wotathon is very likely to produce another team who will have a competing implementation of GrapeRank. The more the better.
