A classic direct marketing analysis is cohorting. That is the timing of response, and grouping people (cookies in this case). Once example would be visitors that visit 10 times in a month. Or people that have visited 10 consecutive days. Time is the dimension. I know you can to this segmentation in Insight. But would like to have the capability in Discover. I have already provided Tim the mock up of what it would look like (and thought I had already posted it here).
