I'm fortunate to be in a mentor-type role to several people and have the opportunity to discuss and study things that I've already gone over hundreds or thousands of times, yet when it clicks for the other person, I find myself incredibly excited over these things I should logically gloss over with disinterest. As you put it, I get to share the excitement of discovery all over again. Its one of the best highs I know. This kind of ignorance is all over the Internet and I'm definitely less likely to be excited and more likely to ignore people. Like the guy who posts Aphex Twin tracks to Reddit 20 years after they were released. I usually discount that guy, but maybe I should be engaging that person and reliving the discovery. Who knows what I've missed out on by dismissing people who don't know stuff that "everybody knows"?
