Moto IQ is an automotive website (
http://www.motoiq.com) that caters to the younger tuner and enthusiast crowd. I have not tried listening to their internet radio shows. They are internet based and I believe previous shows are archived and made available through their website.
In general, I like checking out some of the feature articles, but like most automotive journalism, it gives lots of "we did something this way" without really digging in the painful details and minutia that make difference between a project being successful and someone getting blocked because they lack the knowledge and experience to work through the really tough problems. They do a decent job of handing out some good "how to" ideas and basic automotive understanding.
It might be a good venue for building awareness and enthusiasm among younger potential builders, and it would probably introduce some new people to the whole locost idea.
