Lol, back when that thread existed.
Indeed, it wouldn't "just happen". You have to make an effort. Though I guess what really varies is the degree of "openness" about being interested with one another. Some make it as obvious as going on an app to meet people, where it's transparent that you're making an effort in hopes something materializes, and you both clearly have some interested to begin with, versus just meeting and chatting with someone, maybe becoming friends, but there's not necessarily clarity if they'd ever consider dating you (and might be taken themselves, you just don't know it), or if they even like you and just pretending to tolerate you.
Personally I've been very bad with the former. I'm not the most physically attractive person, so between getting to know a 5 versus an 8, it's kinda obvious who's getting hits and who isn't, be it in real life or an app. And yeah admittedly, I was never the best socially either. Just reflecting, it's a miracle I ever dated anybody lol (personally I only consider 2 of my relationships to have been true relationships, as the first felt weird in hindsight).
Directly answering the question, I prefer to "let it find me", as dating someone to "get to know them better" just feels like an interview where you feel things have to go perfect, versus more casually learning about one another and it feels more natural and safe, and then some can decide by whatever means if something more should happen.
But, it's been finding and seeking other people instead, so... kinda wish it'd be now or never, as I prefer acceptance than mystery .
