Lots of people upvoting it in a short period of time and nobody flagging it? The HN ranking algorithm seems to put a lot of weight into both velocity and flags. A few factors that may have caught people's attention to upvote: it's about an HN company, the author is an HN regular, everything you need to know is in the title, it's written in first-person, and it's a bit unusual for someone to return as CEO.
