Preface: I’m speaking to the non-polyamorous people out there.
I don’t know if it’s due to dating app culture, but I’ve never understood the concept of casually dating around with multiple people. Maybe you can go on multiple first dates with different people since you’re complete strangers to each other before that, but after that you should make a decision to date one person seriously. I would want to put 100% of my time, energy, and attention into that person and cultivate that relationship instead of splitting it between multiple people. And to be honest I kind of understand why people do casually date around since sometimes things don’t work out with someone for whatever reason, and it genuinely hurts to open yourself up to someone and be vulnerable only for it to end, but in my opinion that’s the price you have to pay in order to find a real, meaningful relationship with someone.
