Ask HN: Can we see demographic stats for Hacker News?

Someone mentioned how a lot of the newer browser plugins showing up on Show HN: are Chrome based. Got me thinking it may be interesting to see how the demographics (locale) and tech (Desktop/Mobile, OS, Browser) look for HN. Are 80% of us in America using Chrome on our MacBook Pros or are 20% of us in Nigeria using Opera on our Blackberries?
