The goal of online dating is to get offline as quickly as possible.

Good profiles mentioned characteristics that would probably be true for all of us, such as: I want someone who will make me laugh.

Peak hours for sending a first email through the online dating system tended to be during work (eleven A.M. to four P.M.) and then just after dinner (seven P.M. to nine P.M.).
