I just want to say that right at this moment, as I’m writing this, a space probe has just travelled a total of 6 billion kilometers so it can rendezvous with 4.5 billion year old comet 67P/Churyumov-Gerasimenko, one of the remaining ancient building blocks of our solar system, and the probe is right now entering orbit around it as the first man made object ever to orbit a comet. Some time after completing the orbital maneuvers it will release a lander (Philae) which will touch down on the surface of the comet as the first ever man made object to land on a comet. The research gleaned from Rosetta and it’s companion Philae will help shed even further light on the origins of the solar system and how, eventually, planet Earth came to be.

And we can all follow all of these historical achievements in real time on the internet. Isn’t this at least a little bit cool?

Why should I care about privacy, when I have nothing to hide?


We get this a lot. There are a million answers (our favorite short one is “Nothing to hide? Really?”) but here’s something thoughtful and comprehensive to share with a friend the next time it comes up. The short version? None of the freedom and progress we’ve won over the past century would have been possible without the freedom to change things (starting with our own lives first) that privacy gives us.
