Hi dang, this is unrelated (feel free to remove this reply) but it seems that my post at https://news.ycombinator.com/item?id=9774037 has disapeared? Could you look into it?
Soon, everyone will be able to contribute to unkilling good comments, so fixing these will no longer block on moderator attention. In the future, though, everyone: please send issues like this to hn@ycombinator.com. It's too random whether we'll see it on HN itself! Not to mention off topic.
