There is already a fairly active APUG Forum for pinhole photography. I guess I'm one of those Olde Fartes who has a bit of difficulty understanding the point of having multiple fora and the allure of social networking. I admit to being registered with Facebook and LinkedIn, but the latter seems to attempt to force registrants to fit into pre-constructed categories which I found didn't fit very well with my activities; perhaps because I'm not promoting myself as a business. I signed up after being solicited by a friend in an art club I belong to, but I still don't quite get what it's supposed to do for me.
I do dabble in pinholery, and look forward to WPPD each April, but otherwise I reckon I'm to be written off a curmudgeonly sort!
