My wife and I also met on OKCupid, probably around the same time as you -- Tinder-like features were starting to appear, but the core of the experience was still about reading other users' personal essays and comparing compatibility quiz responses. Of all the services I tried, OKCupid (in that particular incarnation, at least) seemed like the only one that was genuinely aimed at fostering deep personal connections. I haven't been on any of the apps in almost a decade now, but it really seems like the shallow, gamified Tinder model of "swipe right if they look hot" ate up the marketplace, to the detriment of everyone.
