I tried online dating a couple of times and it has been a disaster, the biggest issue is that these people know already to much about you. The natural way of discovering what the other is like is missing.
But dating someone without knowing anything is even worse! I met 2 guys, 1 uploaded a pic that doesn't look like him at all and the other was 10 years older then he said......
I don't do it anymore, I get them from the bar or disco again!
