If anyone actually believed those requests to see code were sincere, or if they at least generated interesting discussion, people might actually respond. But the couple of times I've linked to a blog post someone wrote about their vibe-coding experience in the comments, someone invariably responds with an uninteresting shallow dismissal shitting all over the work. It didn't generate any interesting discussion, so I stopped bothering.
And I think, in this blog post, the author stated that he does heavy editing of what’s generated. So I don’t know how much time is saved actually. You can get the same kind of inspiration from docs, books, or some SO answer.
