Super-habitable planets and volcanism?
In this article: 
There's an interesting discussion on super-habitable planets. But something caught my eye:

"Once you get about twice the mass of the Earth, plate tectonics start to shut down, so try to stay under that amount."

...why? Wouldn't plate tectonics be more vigorous on larger terrestrial planets because of greater internal heat?
