Hackers And Caffeine

| | Comments (3)

A while back I posted a poll on a popular site for Hackers, HackerNews. The question? How much caffeine do you consume each day?

Broken down by age and cups, here are the results:

Interesting, but your technique leaves a bit to be desired. The poll you mention suffers from a self-selection bias and using only the Hacker News site also biases your results. Use these numbers for anything important at your peril.

@Toby, I don't agree - the 'research question' (to use that concept loosely) is to determine the amount of caffeine used *by the visitors of HN* - i.e., nowhere do I see stated that this poll was supposed to be representative of the population at large. Obviously the self-selection inherent in any poll remains.

Hello, great and necessary poll - how about a download link for a super poster?

Recently I created a list of books that hackers recommend to each other -- what are the books super hackers use to help guide them form their own startups and make millions? hn-books might be a site you'd like to check out.
On the low-end of the spectrum, I realized that a lot of people have problems logging into Facebook, of all things. So I created a micro-site to help folks learn how to log-in correctly, and to share various funny pictures and such that folks might like to share with their friends. It's called (appropriately enough) facebook login help
