These have been my experience more or less.
I don't even send messages out anymore, and perhaps my profile reads a little bit jaded. But as a "decent" looking dude (or so I've been told), I get about 2-3 messages a month on average.
And of those maybe 2-3 times a year there will be a girl worth responding too.
The worst is when you actually get into a decent conversation with someone, go back and forth for a bit, and then they straight up delete their account and vanish for seemingly no reason.
It's hard not to be jaded
At least you get messages, without having to send any. when I used it, if someone wasn't responding to a message I sent I wouldn't get any, period.
