The newcomer homepage is a feature to help newcomers get oriented when they first create their account, so they can figure out how to start editing quickly. One component of the homepage is the impact module, which shows newcomers how many pageviews the pages get they have edited, which is meant to motivate them about continuing to contribute.
Adding "sparkline" style graphs that show how the pageviews for the pages have changed over time might make the module more visually interesting. There are also many other potential ways to make the module more interesting, either with graphs, or perhaps with sentences that read like, "Since you edited it, the 'Football' article has been viewed 341 times!"
