Ski lifts, gondolas, and funiculars only work if they bring a skier or snowboarder far enough up the ski hill so they can ski down to the next lift which takes them higher. Simple enough to design. The same principle is relevant when trying to engage fans and donors. These individuals who are test commitment need to travel far enough up the mountain that they can easily transfer to the next level. If you unload them in the middle of nowhere after an initial inquiry or contribution most are not going to head any higher. However, if you provide a map, offer assistance, and help them see the same view that inspires you, the chances of success are much higher.
