You would be surprised what trends on Show HN, not everything is a link to a GitHub repo.

This blog post is not a thought piece, it's something for people to play with, it's the whole point of the post - a practical set of steps to literally fork and deploy a custom version of openfaas.

To me flagging just seems a bit off, like it should be for inappropriate or lewd content. The way HN works, if content is not a good fit, people don't upvote, and it doesn't get seen.
