Yep. It could be gamed as well, creators donating/paying themselves to boost their own rankings. Like authors buying their own books to get on bestseller lists.

Another interesting use case for NFTs is tickets, if you issue tickets for an event at $10 and they end up at $100, at least the issuer can collect a bonus on every subsequent sale... isn't that how OpenSea works?

So a ticket could be auctioned first, and then more is made by the issuer on post-auction sales. It's also very public, so the performer has better information about their worth in the market.

So yeah, digital goods and tickets... that's where it's at for me.
