Has Curiosity made a big discovery?

There has been a lot of buzz the past twenty-four hours about the possibility of a major discovery from Curiosity. However, I agree with Jeffrey Kluger at Time. It is dangerous to pay much attention to these wild speculations, as they are often wrong. Stay calm, and wait for some real information. The most likely possibility is that they have found something very intriguing and exciting, but not Earth-shaking.
