Take one look at one of the "How many cameras do you own?", "Which medium format camera do you use?" or "What's the best non-Leica rangefinder?" type thread, and you quickly realize that many, if not most, people here already have too many cameras and lenses. And newcomers don't come here to buy gear, they come here for advice, and get their gear on eBay, Marketplace or similar sites. Finally, as others have mentioned, money is short for many these days. So no, has nothing to do with a "dying film craze."
