Ask HN: Am I flagged by HN moderator?

Fogscreek's post and mine are submitted at about the same time: http://news.ycombinator.com/item?id=3001173 http://news.ycombinator.com/item?id=3001182 I've gained 8 votes, and they have 5. They are 22 on the front page, I am 51 on the second page. My post was on the front page for about 30 minutes, until it suddenly disappeared. I am wondering if I've done anything wrong, and if next time I can avoid getting moderated (if I was indeed flagged). I believe I am trying to contribute to the community on good faith. So I would appreciate it if somebody can let me know if there are topics or rhetorics I should avoid.
