Low density super-Earths, not so much. Well there already exist systems like CM Dra and CU Cnc as previously-known examples of such systems. Low density super-Earths, not so much.

We already knew of CM Draconis and CU Cancri as well-known examples of such systems (and at slightly higher masses, YY Geminorum). GJ 1214b on the other hand represents a first good probe of a previously unknown region of parameter space. The eclipsing M dwarf binary is more exciting?

In fact, I don't even think it's the most astrophysically interesting find of the project to date (a new double lined, eclipsing binary at the bottom of the main sequence gets my current vote).

Would there even be a surface? As I understand it, the interior of Uranus and Neptune are fluid because of the hydrogen mixing in and preventing the solidification of the high pressure water which would otherwise form an ice layer.
