Nice idea, Skint, but the cost is high to run an ad. Also, while the reach is great with Metro (lots of people) for the idea to work you need frequency (multiple ads). That's why you see the same shit on TV (and in papers) all the time. It's not enough to hit someone once; you need to do it a lot before it registers with people. Sad, but true, particularly in this day and age when there are so many different ad venues.
