I've been programming computers for 41 years and do it for a living ( along with a lot of mathematics and statistics and other endeavors that require thinking and then programming. ) I actually do not have accounts with any "social networking" site... I can hardly keep up with my email! Forums like APUG to me are the best of all, like the old usenet newsgroups, because you can come back and read them later and do it in your own time. It's also astonishing just how much information has been recorded in the APUG forums... a search on any topic is like having an encyclopedia of photography in your fingers, along with a huge collection of experts willing to take time to help. I hope there is a good backup of it somewhere... it is a valuable collection.
If I understand your point, you're suggesting that we just make the pinhole forum more active instead of making a separate group? I haven't been on APUG long enough to understand how the groups and forums are different. But I'll be very happy to participate in either or both!
P.S. cool gallery! Bookmarked to look more carefully later. I like your 2007 bridge!
