Id agree and disagree.
Id agree that the vast majority of women will get an abundance of messages from across the board of weirdos and nice guys. And Im sure women are more than likely going to be picky.
TBF, the men are also being picky. I know when I went on POF, I'd view and faveourite the ones I thought were attractive visually, as opposed to personality. Someone might have fitted my exact thing that I wanted in someone, but may not have messaged them based on looks. And by doing that the men are already narrowing down their pool, because the ones that they might actually have a chance with, arent the ones the men want. I think that's true.
Personally, I spent about a month on POF. I messaged about 5 or 6 girls which I found attractive and seemed to have the right personalities. I probably viewed a good 100 or so women, 30 of which I found attractive (guessing on the numbers, dont quote me). And then out of those 5 or 6, one was attractive ( to me anyway), had a nice quirky personality and could hold a conversation. We're now dating.
So the moral of the story is, if you're just messaging everyone, you arent likely going to get success. Trying to narrow it down to a handful of those who are REALLY viable (not some model that you'll never have a chance with), then you're more likely to be successful.
Thats my experience anyway.
