I skimmed the post trying to figure out what it does and the only hint I got was when it mentioned being faster than localhost. I came to the HN comments to see if anyone would mention what it's for. Seeing your comment, I decided to read through it more carefully. I read the first 14 paragraphs several times trying to figure out what lefthook does. It wasn't until after writing most of this reply that I realized your post went on longer than that, as the picture right before round one looks like the start of a comment thread. Certainly I should have some idea of what your product does that far in to the article.
