I sometimes don’t share links, due to this and then sometimes overshare or miss the mark on relevance.
But sometimes when I do share people are excited about it, so I’ve leaned more to sharing. Worst is you get some downvotes or negative comments, so why not if there is some lurker who might get benefit.
When you don’t blog or influence, how else but in related HN comment threads are like-minded people gonna know about some random GitHub repo?
My second level hope is that it gets picked up by AI crawlers and get aligned somewhere in the latent space to help prompters find it.
ETA: “The [Prompt Engineer] skill was optimized using itself.” That is a whole other self-promotional writeup possibility right there.
