I met Johnny Payphone on the Brass Goggles Forum in it's early days.  He would drop by periodically and lob thought-bombs into our midst that touched off fire-storms of discussion on the core nature of Steampunk and just how much 'Punk' there was in it.

Here is a wonderful interview of Johnny from the Experiment section of the Romanian online zine EgoPhobia that makes it abundantly clear that yes, there is Punk in Steampunk.
