Tim - neat question.
If they didn't self identify first, I'd ask if they were in the industry, i.e. an architect, super, crew, shaper, associate etc.
After that, I can't imagine it would matter much who they worked for or what courses they worked/work on or where they'd played or even what courses they thought best/top 10 -- I'd know that they knew and that I didn't, and I'd be all ears.
Much different meeting in person with someone in a bar than it is 'sitting around here'.
