I agree with above sentiment. The first thing I saw when I went to a new lab a couple of weeks ago were two young girls handing in their negatives taken with a Holga, if that's what it takes for labs to stay open and for the next generation to be excited about film photography then I'm all for it.
This has already been beaten to death here recently. It amounts to a drop in an almost-empty, leaky bucket. Lomo shooters won't make any difference and won't turn the clock back for film.
