There have been numerous threads on BG over the years like the current 'Would You' topic involving interest & availability in creating a real steampunk community. Ones I recall off the top of my head have included a free-standing small town, a farm community, an abandoned factory, trailers & train cars, etc. Most or all of your questions have been answered in those threads, you might want to use the BG search engine to read what has been written as background material. markf
That's exactly the problem, it's everywhere. How many of those people are still interested? How many of those people are going to commit to the project? And if people are put out by answering these questions again then they can just copy/paste to their heart's desire, or not answer them. Seems to me that everyone is singing: "Wouldn't it be nice if we were older (or richer, or whatever)," but not much else. This is a call to action, and it will be heeded or it won't be, that's the long and short of it. I can't say whether or not the community is mature enough to handle the responsibility; this is merely the first test to find out.
I have considered beating the pavement, interviewing every single person who's shown interest in the idea. At that point though, it stops being a democratic thing, and starts being my thing. I'm going to stay away from that for now, I'd much rather everyone come together on this.
