Self proclaimed, perhaps. There are quite a few other fans, some of whom are on this very board, who would be more qualified to represent long term DS fandom. I had never seen or heard of this guy before. I checked his Facebook page. Other than having Marie Wallace and a couple of fans as friends, there wasn't a lot of DS on his page.
I did watch the video interview. I'll refrain from commenting until someone else has seen it. There are also video interviews with KLS, Lara, Diana Millay, Jonathan Frid and David Selby. Obviously, it's archival footage but not everyone will be savvy enough to notice.
