It's not just you, but personally, I've never been interested in getting rich. For me, HN is a replacement for slashdot, after every second comment there was racial slur copypasta. I'm here for the technical articles and wacky projects like this.
For myself, opportunities to hack on fun side-projects are rare but I cherish them. Geeking out brings me satisfaction and joy. I've put a couple of fun projects on github and every fork & star is a little hit of shameless gratification: unlike karma on these blasted social sites, it feels like I've done something tangible to bring a smile to somebody's face. Because I did! That's not an intangible, it's good for my mental health!
