My question about the accuracy of the smoking and drinking habits depicted on Mad Men has received a handful of answers. The first cites an ad exec who was around during the time period and spoke of first-hand experience. Later answers cite personal experiences of varying degrees of utility.
The difference: the first answer (and the one I accepted) contained quotes from an interview with USA Today about the accuracy of the smoking and drinking habits on Mad Men. Duh. The later answers were more secondary source material, but interesting nonetheless (to a degree).
Because there is some valuable, if not interesting, information presented by these answers, I hate to see them languish. One of the answerers does go off on a personal tangent that degrades the quality of the post, but the newest one by Becky is fairly useful.
What can be done to keep these users (two of which were fresh to SE sites, one is a Super User vet) involved in Movies.SE? Is there any generally applicable constructive criticism to offer answerers providing an answer that is either second-hand or anecdotal?
