As a guy who met between 75 - 100 women online from the ages of 18 and 28, I can safely say it is not a waste of time if you know what you're doing. And frankly, most people don't know how to build up a relationship/rapport/attraction online and they take way too long to build up any interest and ask someone out that the person just loses interest. I've seen below to average looking females Tinder accounts and they get literally 100x more messages and interest than guys. So, unfortunately, men are already at a disadvantage from the get go. Although it's been a while since I've done the dating game, I'm guessing it's all changed now.
