It’s D-day. Jon vs Arthur. Brotherly rivals since childhood, now we meet to compete in the most extreme environment on earth, apart from those underwater volcanoes: the Internet.

Once a week for the next year, we’ll each create a revenue-generating website, and pitch it on video here. The rules? Build them ourselves (no help from friends). We can include or sell content or products by others, as long as they get their rightful share of any revenue. And keep costs as low as possible, ideally to domain registration fees only — about $12 per site.

The aim? Make back our costs.

The real aim? See what happens and learn from it.
