Defending hook-up culture?

Here is something I would never have expected, but I guess should have. Amber Madison, the Tufts Daily sex columnist, writes in "Why We Hook Up":

Hooking up doesn't have to be a one-night stand; it can be more of a 30-day, risk-free trial. Before you invest too much time, money and commitment into something you get to try out the product, and see if you like it.... Girls "embrace hooking up" because it allows us a sense of comfort that dating cannot provide.
