OMG Jake Page, just brilliant! I saw myself in so many pieces of your writing. God, how many Udemy courses I purchased in the past 😥.
I concur completely on your article, especially on "Pick an issue that's slightly out of your league". Correcting a typo is fine once or maybe twice, not more. As you say, it doesn't add any great value, except for a feel good factor.
Open source in Product Hunt was also new to me. Thanks a lot for sharing your experience.
