There's a Tinder-style dating app for smart-fridge owners now. You share photos of the contents of your fridge to decide if you're compatible. I suppose the advantage of this is you'll screen out all the people who can't afford to blow 4000 dollars on a fridge that can connect to the internet, if that is the sort of criteria that matter to you. Someone should make a dating app for book lovers, where you post pictures of your bookshelves, or your TBR pile(s).
