Jeff Veen explains why he digs Wikirank:
… it helps people find stories in the data. One of the great things about the web is how measuring tiny behaviors reveals patterns that tell stories. The data we get from Wikipedia is no different; as we started playing around with the numbers, we saw loads of interesting shapes emerge in the charts.
For example, just do a comparison on the past and present lead singers of Van Halen, and you’ll see an accurate visualization. The possibilities are endless.
