I don't think it matters what your initial spark is to get you started. Whether its envy or inspiration, as long as your doing it and enjoying it. If months after getting your project up, and the first thing you can say to someone who asks you why your doing it? And you respond like "for Google to buy me", then maybe your envy has become a bad thing, or at least its made you kinda shallow. Otherwise there's nothing wrong with reading that youtube buyout article and then choosing the next day to spend the day thinking of an idea you'd be happy with pursuing over the next couple of months.
