To be honest with you, my interest in NASA has not changed much. It has always been very high. What APOD has done, is provide much better AWARENESS and ACCESS to interesting areas at NASA, and Very interesting astronomy photos. And that is not a small thing!
Many decades ago, a high school friend ground his own mirror, and we spent one night freezing our toes shooting photos of a lunar eclipse, which I developed that night. My toes and the weakness of the telescopes put an end to my participation in first hand astronomy, not my interests. I actually took a course in astronomy some four years later, enjoyed the textbooks, but dreaded those freezing telescope nights. To freeze my toes for a few specks of light on a cheap telescope owned by a two bit university? When the textbooks show much more interesting photos from places like Palomar?
I visit your site almost every night since the mid 1990's, and my toes don't complain! You guys are wonderful! Absolutely Wonderful!!!
