Perhaps you've heard of Ashley Madison, the website that allows married people to hook up with other married people for discreet affairs. (We hope some of them weed out potential sex partners based on the way they spell "discreet" because "discrete" in that context is a serious turnoff.)

The Main Line came in first, which sounds about right somehow, though we're not sure why. What about within the city boundaries, though?
