I don't have a question, but an observation, and some unsolicited advice.

You said "AMA" hours ago, and haven't returned (as of my comment timestamp) to answer the questions that have been posted here. On HN, the story may fall off the homepage before you have a chance to come back, which would limit the audience that would see your answers.

I've upvoted it, because I think it's an important study and the conversation that could be had here in the comments may help someone. But I'd urge you (and anyone who says "AMA" on a popular site) to check in every 5-15 minutes for a few hours, just to keep momentum going.

Good luck, and thanks (in advance) for any answers you may offer to the other comments!

[Noted]

It looks like it might've been more of a time delay issue as it seems like they've answered lots of stuff in the intervening hours. I'm not entirely sure how much answering questions late at night actually affects the audience. I do definitely hope that this post stays relevant because it's always great when the authors are around to answer questions on posts.
