After recovering from a Denial of Service (DoS) attack, the Atheist Survey is up and running again, at http://www.atheistcensus.com/
You can also see the results so far. Interesting to note* that the gender breakdown shows 25.3% female for the entire survey, and 29.5 for Canada. (Also maybe worth noting that the # of respondents for Canada is >2000, which puts us ahead (per capita) of the US, at ~15000).
