Seconded. Additionally, I'd love to see a distribution of comments/upvotes by date of submission (such data I think could be gleaned from HN search). My eyeballs tell me posts submitted within the first 2 or 3 days of Apply HN got much more traffic/discussion. Certainly it is possible that those first posts warranted such discussion and subsequent posts did not. Or maybe I'm completely wrong in my observation, which is why I'd like to see such data.

Also, after ApplyHN became randomized (around midway thru the experiment) it seemed like discussion dramatically fell again, but it was definitely tough to tell since refreshing showed new applications every time.

Fun experiment though and I'm excited to see what types of projects the community picks.
