I'd go so far as to say the VAST majority are not.
"back of the napkin" logic:
~2M FAANG employees (source: Gemini & this includes all types of employees...is your avg Amazon delivery driver regularly reading HN?)
~10M HN users (source: Gemini (via HN post :)) )
You mean 22k unique visitors per day making 13k comments and tons of web scraping bots?
Data from 2022, so if we multiply it by 2 I would say 26k real hacker news users.
Wasnt the stat that for 1 creator there are 10 commenters and 1000 viewers?
