This sort of content feels good in the immediacy but ultimately lessens the quality of hn. I'm not concerned about this post specifically, but I feel that we should be more critical of things like this making it onto hn. I come to hn to mostly hear about tech, tech advances, startups, etc. I don't come here to read feel good (and admittedly, very cute) stories. They have their place, but I feel that place is not hn.
Even the Wall Street Journal has lighthearted “A-hed” articles, which have occupied valuable space on their front page for 83 years and counting.
