Changes in the last year have made Ok Cupid a bit more like Tinder, focusing more on swiping and eliminating the ability to message a user without matching with them first.
You can still send a message -- it just won't show up in the recipient's inbox unless you match.
If you want to play the odds when it comes to online dating, you need to be swiping where everyone's swiping.
On the upside, the profiles are brief, which allows you to make decisions quickly.
However the rate of overly confident males tends to be higher than I've seen on other apps.
