Someone asked today about the best time to ask a question (a question that has come up before) and it got me thinking that if there is a best time, then there is probably a particular geographical region or set of regions that provides more answers than others. I would assume this is most likely North America due to the companies that rule most people's lives in at least the SO and SF domains, like Microsoft, Adobe, and Apple, but are there any stats that could be used to analyse this?
I think it would be interesting to see the patterns as those in high activity regions would face more competition in answering questions than those in low activity regions, or more importantly, time zones. It could give a whole new insight into some of the top rep holders.
As a corollary, the times of day that people answer and ask questions might also be useful on some level.
