I'd like to point out that just because a planet is larger than Earth-standard, that does not necessarily mean that the planet will have a higher mass than Earth. The planet may be composed of significantly lighter elements than Earth, giving it a lower, Earth-like mass. Similarly, a planet smaller than Earth, but composed primarily of heavy elements, could still have a roughly Earth-equivalent mass.

Bear in mind, I'm not trying to discount the point of this blog post. People absolutely should be sure to specify this stuff when creating articles for planets.
