I'd like to know the demographics as well. In the US I knew more LF users under the age of 35 than over, and I lent out some of my pieces to fan the flames. Though I recently crossed that age divide, I think I can still safely speak for them. We sit behind monitors all day long, so playing with PS is nice, but reminds us of work. On the other hand, my other hobby/income, ham radio, was just the opposite. Practically nobody younger than me got into it except as part of an emergency management group of some sort. The accessability of LF due to eBay and the fact that you can hand someone a 4x5 slide and say - 'that's about a half a gig of data in analogue form there' as well as the chance to do something completely different... oh yeah, it's also a good way to meet women (as opposed to girls) in NYC as they'll break the ice.
