I had this idea about 8 months ago and made a really crappy prototype (which I posted to HN). Sort of like Rotten Tomatoes for everything, based on structured Wikidata data.
I had a bunch of new ideas so I've been working on it a bunch over the last few days, and I think this version demonstrates the potential a lot better.
I also had some fun doing a passwordless sign up flow in a way I think makes sense for most websites these days. All you need is your email to sign up, with optional passkeys support.
Please let me know what you think!
