I think that we have to adequately define "influencer" and what it means to have influenced a decision.
For example, while I am not at all influenced anyone's look, I am influenced by peer recommendations. I certainly can't say that I would have found Stephan Schneider or SNS Herning without having read about them here on the forum. And I'm reasonably sure that Engineered Garments and Wings+Horns would not be as popular on the forum as it is without my having championed it in the early years. Does this make me both an infliencer and one of the influenced? Or are we talking about something much more specific?
fwiw, I get emails on the official Sty;leforum account all the time refering to us (or rather, the forum, as a whole) as an "influencer".
