I was looking at Google Trends for "Kubb" and two things stood out. First, the graph:

First, Kubb is incredibly seasonal for search traffic. That isn't terribly surprising, but also worth noting that Kubb websites will also have a seasonality to them. I expect sites like Planet Kubb will not be nearly as seasonal as the year-round hardcore Kubb players are here.
The big question for me is what happened in 2005-06? That year shows a 2x difference in search traffic on Kubb. Ideas? Notice that seasonality didn't impact a huge dip either which makes me think a lot of people got Kubb sets for Christmas in 2006?
