Having a project hit the front page of Hacker News is a noble goal of any software engineer. Someone posted about ArtBot and it got up to position #5!
I believe Reddit pioneered the “TIL” meme (TIL, short for “Today I Learned…”).
Over on HackerNews, someone posted an interesting discussion related to a collection of “Today I Learned” notes on GitHub, featuring all sorts of interesting coding tidbits. It goes back over 8 years!
It’s such a brilliant idea and I think I’d like to adopt something similar myself: if I learned something new and interesting, I should post about it.
