The tour page of Stack Overflow says that
Stack Overflow is a question and answer site for professional and enthusiast programmers. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about programming.
Since the above description says it is a site for professional programmers, and we have a lot of people here as well (which makes a society :P), so can we say it is a Professional Society?
Definition of a Professional Society (According to Wikipedia):
A professional association (also called a professional body, professional organization, or professional society) is usually a nonprofit organization seeking to further a particular profession, the interests of individuals engaged in that profession and the public interest.
(If you have any of your own definitions for a Professional Society, that will work as well)
P.S. I was doing my resume and I have to answer some predefined questions, one of those is Professional Societies, so I was wondering if I can write about Stack Overflow there? Since I have been answering a few questions recently and reading a lot as well.
Thanks for looking into the question! :D
