So I will chime in as a 'pin guy'. I don't wear them on my clothing but I do pick up cool pins I see for properties that I don't want action figures of but want to support or whatever. I have a flap on one of the messenger bags I use at cons that is festooned with pins. I wouldn't go out of my way to get this exclusive pin... but I have a pin of Castle Greyskull, for example.
I used to adorn my SDCC lanyard with pins, but that got heavy and a couple fell off so I stopped that
Disney people know tho... there is a whole Disney pi-trading world that makes us here look like casuals.
