When you write something and put it out there into the world, you never know what will happen. It may get an interesting response, or it may drop like a stone off a cliff.
And then sometimes you get something totally unexpected, like when Robert Krulwich wrote about Apollo 11 for NPR, and got a response from someone with some experience about it*.
The response is fantastic, discussing why we need to continue to explore the Moon (see the title of this post!)... and though I have disagreed with the author of that response from time to time, he and I are %100 on the same wavelength here. Go read it.
