Users flagged this story, presumably because some of the comments look suspiciously like astroturfing. I'm going to give the benefit of the doubt and override that in this case, but guys, you need to realize that you can't promote your stuff on HN that way. Astroturfing accounts get banned, and usually we'll ban the submitters' accounts and the site as well. Even if we don't do that, HN users—who have a nose for this sort of thing and really don't like it—will react negatively to your post, and that's definitely the opposite of what you want.
I have a feeling it was just your friends trying to give you a boost, which is very nice of them, but please tell them that HN is the sort of place where that doesn't go over well. Instead, learn to let your fine work speak for itself.
