In a lot of irl spaces where I live, women can enter on discounted prices or for free, and this is done by the ownership to prevent the bar or club from becoming a sausage fest. Online dating doesn't have that, so it ends up with 80% of the userbase being guys, and all the issues that causes.

I'm not saying that online dating needs to copy that model and start getting gross/sleazy promoters, I'm just saying there's a reason why it's used at clubs and bars. A more equal gender split would do a lot to improve the online dating experience.
