Outside of paying for placement (which I am quite certain has not happened for this site), Google puts many factors into placement, one of which is how many other web pages link to this site. Linking to this site on your cache page helps a lot, as does mentioning it When you are discussing caching in other forums or on social networking sites like facebook or anywhere else you can.

It's great that we are near the top and that gets people in the door, but keeping people here is the next step. I still think there is a lot of room for improvement in the form or articles and stories.
