Very low response rate unless using carefully tailored messages that require one to behave like an empty headed idiot to get to home base. Easier to chat up the soup chikkins in the local dive and in person one can spot the people with problems more easily. Great place to collect a stalker. Online dating used to be great - maybe 10 years ago - now it's a waste of time - women are bombarded with junk. The women are not fake. Didn't see any fake profiles. And they're not all ugly. But the response rate is close to zero. And your details ARE NOT CONFIDENTIAL!
