The significance is this: it's very likely that there are a lot more such planets a lot nearer to us.
This is because Kepler can only detect planets which lie in the same plane as earth and the star so the planet occults the star.
Assuming random distribution, there's probably thousand fold amount of off plane planets.
There are 259 stars within about 30 light years.
Communication could be conceivable with such distances...
