I dunno. I think it's all over the place. I think you get the street style "personalities" that either work or worked for someone of note and have a cult following. Then you have the real/fake caste system (i.e. real writers vs. bloggers, real photographers vs. street style cameras, established brands vs. "of the minute iGent boner" brands, etc). Finally you have people that are involved with the marketing/manufacturing game.
I know of people that have gone that range from buyers to people that supply fabrics and other materials to dudes that just want to see it first hand. I think it's safe to assume it's all walks of life from all of the "menswear scenes." Naturally this means that you'll get the venerable and the laughable at the same time, and likely in equal doses.
All that said I know Fok is there so maybe he can shed some light?
