Season 3 will air on Discovery channel proper, and it's allegedly going to be slightly less ADD, but you know it probably still wont be a show that's really about motorcycles. You need to put it in perspective a little. If we crafted a show that we thought was relevant, it would bore the pants off most of the people who like watching the reality BS they generally air. So it's got to be somewhere in-between. It also will draw a lot more inexperienced fashionistas to classic bikes.
Stop thinking of it as diluting something pure, and look at it as an opportunity to sell your bikes for 3x what they're really worth, and/or get work out of fixing them when the trustafarian gets stuck with dead batteries/clogged carbs/no fork oil.. etc.
