While the system itself is nothing extraordinary from a detached, theoretical point of view - we are aware that there are many planetary systems in the universe of all sorts and sizes - what makes this news so impressive in my opinion is the thrill of actually witnessing, almost tangibly, such an alien and wonderful system, excitingly different from our own (read the article in detail, fascinating stuff), amplified by the fact that these planets are relatively quite close.

Basically, the system is so peculiar and close to us, now that we have actually discovered it is difficult not to be fascinated by it, even though we know it's nothing to be perplexed with in the grand scheme.
