I'm thinking of starting one devoted to photographic tie pins - there must be a lot of people out there who would like to debate, trade, boast about their collections. But RFF is down and I can't do that right now.
I think one on all the different aftermarket lens caps is a more pressing need.
I do use a digital device in my photographic pursuits when necessary.
When someone rags on me for using film, I use a middle digit, upraised.
