Yeah that helps of course. There's many different ways of coming at it, but to me the most obvious one is a technical interest. If you're a technical person then presumably you have an interest in technology and it would be a little weird for a technie no have no interest in exploring technology. Aside from being fun, it makes you smarter, more resourceful. All of these proprietary companies want to lock down everything and basically the only thing you can learn from it is look at the gui and see what buttons are available to you (to make a small over simplification). The linux world is radically different, you can see how things work, it's eye opening.
