Every day, I realize that more and more people here know a lot more about tech than I'd expect a random set of Jews to know. It makes sense, but of the regular users, what percent work in or have worked in IT?
using @Aarthi's metric, I counted 12.5 people in the top 36 (first page) active this quarter who are NOT members of a technical SE. The .5 is one user who is only a part of Mi Yodea and LaTeX user group (which though technical, does not imply IT industry).
So a super-majority of highly active users are in IT. It seems that higher ranking correlates with IT (there were more in the top 12 than in the next 12). I wonder why this is. Maybe more time in front of a computer or more google-fu?
