Is there a time that you have noticed that has more traffic in SO (i.e. more views for a posted question)?
I suspect that due to time zone differences some of the questions does not get the as much views as they deserve.
This knowledge might help deciding when I should post questions in order to get a better chance for a good quality answer.
Edit:I guess this will be influenced by When do users post answers (before/after/during work day)...
