I'm the author of a popular open-source project for my programming-language-of-choice. Before I launched it ~3 years ago, I reached out to a well-known OSS guy in the community. You would probably know his name. I wrote to him asking if he had any feedback on my project, since I'm about to release it, and because he had a similar project that didn't get much traction. He didn't reply...fair enough, I'm sure he's a very busy guy. Fast forward a few months, I launch the project and it blows up on HN for a few days, and on twitter for a few weeks. The majority of people love it! But sifting through the feedback online, I'm shocked and disappointed to see is the very person I reached out to trashing my project publicly in comment sections and on his twitter feed. No constructive feedback, only how the project itself was a horrible idea, and the code was disgusting. I was dumbfounded...before, I wasn't worth 2 minutes to reply to in an email, but now I am worth destructive criticism on social media by the same person? I waited a few months and sent another email asking for advice on maintaining the project. No response still. Yet every now and then, to this day, I still see backhanded comments by him about my project whenever someone mentions it to him on twitter. Some people are toxic, petty, and childish. I don't really have a lesson from this, but that's my little story.
