Would there be some way to see what percentage of the front page meets those qualifications? I don't browse /new very often, so I have less of an idea of how representative that is. It would be interesting to see if they trend similarly.

Thanks for the cool project!

Yeah, that's probably the main limitation right now. This is measuring /new, so it's every submission rather than just the stuff that makes the front page.

lcamtuf's survey (linked in the footer) was looking at the front page, and the number there was quite a bit higher. So there's likely some effect from voting, although I haven't dug into that yet.

I think Algolia has a way to filter for front-page stories, which should make it pretty easy to add. I haven't tested that yet though but will certainly look into it!
