I think for *some* it depends on how involved you are in your organization. If you are someone who plans to be an advisor, international officer, or the alumni member who is volunteering for everything in the AA, having a SO who understands that committment and dedication of being in a GLO may be beneficial.
Am I going to go up to every guy that I think is attractive and ask them, "So, what fraternity were you in? Oh, none....well, see you later!" ? I don't think so.
