Crazy Blind Date allows people to gamble with a blind date, in the knowledge that they'll be able to "mark" the person who shows up for presentation, punctuality (or even "no-show"),  fun and other factors once the dates over...

The dates should be safer too, as the meeting point, time and people involved are recorded. It's only for a few states in the USA so far.
