I think that the photographic community needs to promote film more in the younger segments.
I know a lot of young and up and coming photographers that are fascinated with the subject, but knowledge and teaching is scarce (except from when you are on the Internet).
The only thing that can keep things going, is that it exist a marked for the companies supplying film and analogue material, thus, stuff like lomography can only benefit the situation.
I am pretty sure that if you'd shown a 18 year old the process on _how_ to make a photo, from pressing the shutter at a location, to a finished print (from a scan or a wet-print), that person would be fascinated and interested to learn more and shoot analogue himself/herself.
The problem is, perhaps, that there are very few younger people being thought this these days, so the knowledge and the marked keeps getting smaller.
Maybe have a mantra "teach one youngster per year on how to shoot, develop and print using film" would be an idea?
