Would agree wholeheartedly with this. Once you drill down into a person, you will eventually find an aspect of them that approaches life in a way you do not, and in a way which increases your appreciation for the depth of human experience if you listen closely enough. The signals the author are clued in on here are superficial to me. Idiosyncratic consumptions, a controversial political take or two? Sure, those can tickle one's curiosity, but they are only entrances to possible points of uniqueness and can be easily faked. Obviously you can't know everyone, nor should you want to, so these are just proxies the author uses to find people they want to spend their limited time with rather than in my opinion actual "not-boring" people.
