Mark Brooks: As a student I worked at the Simi Valley Ford dealership selling cars one summer. Seasoned salespeople liked to remind me that 'buyers are liars.' I refuted this but it seems strangely relevant in the dating space. Our buyers are liars, only insofar as they really don't know what they are looking for. Beyond the basic showstopper questions, don't we go a bit far by asking so many questions and offering up so many search filters?
