I occasionally visit a blog by Trevor Marshall who is modelling a Canadian branch line in S Scale called Port Rowan.
This post is not about his layout but I present this recent post with his thoughts on a possible direction to keep the hobby from dying away.
Trevor's post is based on a speech he gave recently at a convention and I ask you to have a read and to also read the comments at the end of his post, thought provoking, I believe he may be onto something.

There may be something here and in the comments for exhibition organisers to think about as well.
