Ask HN: How many people are on HN?

Here's some data from Alexa: http://www.alexa.com/siteinfo/news.ycombinator.com

Alexa is not even close to being accurate on tech-related sites. A 3,000 alexa rating on a non-tech related site means the site is attracting at least 3 million unique visitors per month.

My best guess is that HN attracts around 300k - 500k uniques per month.

I think the very best submissions got something like 2k points. Since those are really interesting, I would assume a significant proportion of the readers upvoted them, let's say 20%. It would mean 10k unique registered visitors a day. I don't know about the non registered visitors, but let's say for the sake of guessing that they are 10k, that would be (very approximately) 20k unique visitors a day.

I haven't looked at the numbers. I should, but there are too many other things to do, and we worry about quality more than quantity.
