This is a great profile of Kevin Rose, someone I like to consider a friend. The below really sums up his enthusiasm and excitement for ideas in their purest form. His enthusiasm is utterly infectious.
"I have so many random ideas," he says. "They're great little lifestyle businesses where you could make a couple hundred thousand a year. But they're not necessarily the things that you'd ever invest in or spend the next four or five years of your life battling for the market." So he gives them away--constantly.
