Good taste is better shared.
The point of learning a palate is not to make a better list. It is to find the person whose taste genuinely overlaps with yours, work out where the overlap sits, and recommend into it — which is a very different problem from averaging two sets of favourites.
The demo on this site shows the shape of that with invented people. You can see how a match is explained and what a shared recommendation looks like. Nothing in it is real: no account is created, no invitation is sent, and the people in it do not exist.

Matching, plans and invitations are live features in the private test. They are not simulated here, because a browser page that pretended to send an invitation would be a worse thing to build than one that admits it cannot.
