What is the current monthly user count on Hacker News?

That's for the entire domain or just the "root"?

I would guess the root traffic to ycombinator.com is quite insignificant in comparison.

Anyway, visits != visitors.

All of that could be discovered through the API with a bit of scripting. Fetch the latest item number and decrement until you get to one month ago.

All of what? They asked a single question about a single data point and your suggestion doesn't even make sense.

I am deeply humbled.

... or maybe you are an AI bot? Or a NS one?

Me and you. Thus at least two.
