Apropos of nothing, I notice that your comment is post number 30 000 000 on Hacker News. Congratulations, I guess?

I had the same thought. Though, it appears that post numbers stopped being interesting by 10M: https://news.ycombinator.com/item?id=10000000

I was surprised that the post numbers appear to be sequential, and that there would be ~30M. Over 15 years of HN, that's ~5K posts/day, and about 200 new posts/hour. Things accrue. I'd estimate that HN is well north of 300K readers/day ... https://news.ycombinator.com/item?id=9219581

edit - it looks like each comment has its own item id. So posts are both new items and comments. That makes more sense to me in terms of scale.

Close to 9 years for the first 10M from https://news.ycombinator.com/item?id=1 to https://news.ycombinator.com/item?id=10000000

About 4 years for the next 10M from there to https://news.ycombinator.com/item?id=20000000

Approx. 2.5 years for the 10M after that to the current total number of posts and comments we have today.

That's pretty interesting to me.

I wonder if growth will continue, and for how long HN will be able to sustain its excellent signal to noise ratio.
