I might consider joining, even if I don't own a single canon or nikon. I'm always looking for places to spam with my photos.
And yes, the best way to convert people to using film is to show them what film can do out in the open. Not some place under the rock and then scream at them when the word scan... is mentioned.
I picked up film 1 year ago by looking at enough very pleasant looking film photos. Not to mention revisiting my old photos. After 9 years of shooting of digital. If you show compelling photos, enough people will come and more people might use film. It might not save paper etc, but at least it might prevent more lines of film from being consolidated.
