Obviously, the comfort level would have to be there, which is why I think the sites use the matchmaking approach. I know with my kids, they know and love their babysitter, which is a huge incentive to stay with the same person. I would think that once you've established that you like a sitter, you might try to go outside the system and make a side arrangement, so I would guess that you'd want to have a mechanism to request (or deny) a specific sitter or maybe a way to rank them.
