Now that dufnering is going mainstream I think you should start a Dufnering website.
You could blog about the best places to practice dufnering.
People could post vacation pics from around the world: "this is me and the missus dufnering at the pyramids".
You could have a whole section about the best food to eat while dufnering.
And the final, best section would be famous historical dufnering sites. I'm sure somewhere in the US is a plaque stating "Abe Lincoln Dufnered Here".
You know this could be big...maybe even as big as dufnering.
