> There's no stats page but last I checked it was around 5M monthly unique users (depending on how you count them), perhaps 10M page views a day (including a guess at API traffic), and something like 1300 submissions (stories) and 13k comments a day.
Forgot to mention, but "I was on the HN frontpage for X hours and got X views" doesn't always translate to the same happening for everything. Some topics are more interesting to the people just browsing HN, than others. I'd expect an article titled "I spent $6 Million On Google Ads Last Year" to be significantly less interesting than "MSFT is forcing Outlook and Teams to open links in Edge and IT admins are angry" for example, where the latter would surely gather a magnitude of more visits than the earlier, even if they would spend the same amount of hours on the frontpage.
Some content is simply more interesting for a broader audience.
Hacker News has 3.4 million users per month and 350,000 users per day, with 4 million pageviews a day. There are just under 1 million registered accounts, with several hundred added each day. Users post around 1,000 articles and 6,000 comments to the site per day. https://blog.samaltman.com/2017-yc-annual-letter
Not the OP but they were referring to the whole site. So definitely not millions, but the number is probably higher than you think.
From the blog you linked, the number of interest is 18k. 12k are only those with HN referrer headers. In reality, many setup strips that header so you can't track it exactly right. The author did mention they averaged 50 views before.
A big part of it are reposts. From my own submissions, posting to HN resulted in tons of different origins. Public ones like reddit, twitter and private ones like newsletters, dashboard & chat messages. You'll also be surprised by the wide variety of clients people use to access HN.
They also used Google analytics to track the numbers. Most people in HN block it either through the browser or an extension [0]. In reality it's probably double the traffic.
Don't forget to account for scraping & crawling bots. That's another big source of traffic that the author didn't track.
This person says they got 12k visitors over a day:
