Interesting find.........the closest to an earth-like planet ever discovered; a planet which is 7 times bigger than earth and has temps at 400-700º F. What does that say about the search for an earth-like planet?

That we haven't found many planets yet

And that the larger the planet is the easier it is to find, and that the close to its star a planet is the more it effects its star and the easier it is to detect the relatively tiny wobble it causes in the star.

What does it say about the uniqueness of earth?

Almost nothing. We have discovered less than two hundred planets, in a universe that literally contains more stars than grains of sand on a beach. The earliest plants that we found were all giant planets (maybe "brown-dwarf" failed stars), that where much bigger than all of the planets, moons, and planetoids in our system combined. They were also all close to the star they orbited. I'm guessing that this isn't typical of planets in general, its just those are the easiest to find.
