I agree with Bob Heil and others similar views. I don't have a problem with 2 rail 0 that the others who want to change have. I enjoy the nature of the experience, and the uniqueness of it. There is a totally differnent and higher level of satisfaction in it.
I do promote the hobby in a small way. I've had the local NMRA over and have open houses for the locals 4 or 5 times a year, and have had an article written about the layout in an NMRA regional newsletter. I can understand why some would not want to open their homes up to strangers but I do it without a second thought.
I've written a few articles for OST and should have something ready to go within a year or so. I don't particularly like writing formal articles but it is something I can do to help. Nothing about the experience of writing formal articles or getting published really gets the juices flowing for me and I suspect the same for others.
I've posted videos and photos here and on Youtube from time to time. The person who posted that "0 Scale" should be in the title of Youtube videos is a good idea.
I think there is a balance between promoting the layout and modeling with photos and videos, and a perception that people are promoting themselves. I think this perception seems to permeate 0 2 rail more than 0 3 rail. I don't know why. Terms like "fishing for compliments" seem to come up every so often in discussions I hear offline. Personally, I agree that we could be posting more videos and photos.
Chris' post about promoting the hobby and how it can be a distraction from working on the layout is really valid.
If you are into promoting 2 rail and enjoy it then I'd say go for it. If it becomes a drag for you, then focus on your trains and just enjoy the hobby in that way and let the other stuff go. If I'm the last 2 railer standing, I'm okay with that. It just means other people are enjoying something else.
With patience, I've certainly been able to obtain everything I've wanted and more than I need in 2 rail, so I don't see the problem there.
You hear all the time how impossible 2 rail 0 is to make work. I've heard all of the myths and even believed them when I was in 3 rail. Contrary to what many believe, my experince with most 0 scalers is that they have a "can do" attitude when faced with challenges. I've made 2 rail work pretty easily for me and have blown through most of the myths, so maybe some of us are not just mere mortals.
