The response to this survey has been great! I appreciate all who took the
time to respond. I am posting this again as I need a larger number of
responses to go by for statistical purposes. (At least 30 in a sample
to model a population, etc.) Thank you. :-)

In this case the population of interest could be the individuals who read this group and wish to participate in this survey.
