This handy, dandy little application will allow you to find other Wii owners in your area. It’s a pretty nifty Google mashup that tracks where Wii’s are around the world. You can click on the “Request” button once you’ve found someone in your area. I’m not sure exactly what happens after that, as you have to be registered from that point forward (and I don’t own a Wii).
So, in the event you’ve just been majorly powned in Call of Duty 3 or online bowling, you can now find the the town where “L3371-3873821” lives and Jay and Silent Bob’em! (assuming, of course, you haven’t gone Jay and Silent Bob on yourself playing the Wii)
