I totally agree:

When you are genuinely curious, the sole reward you seek is nothing but knowledge. It can’t be money, fame or power. It can’t also be others’ appreciation or acknowledgment. When you seek either of these rewards you lose track of curiosity.

If that's the definition of Curiosity then I'm defined by it. I always want to know more about the things that I want to know... Mostly are useless things but the reward I seek is knowing it. Not anything in the way or after that.

Maybe that's why TV Tropes is one of my most favorite websites. Ultimate database of knowledge in one place.
