You shouldn't have to justify promoting analog photography anywhere on the net. Facebook is Facebook; if you don't like it, don't go. But there are a lot of great photographers out there, and surprising as it seems, many of them have never heard of APUG. Meet them, greet them, and by all means invite them. There's more than enough room here for them. But please don't denigrate them.
Rant over. (hm... somebody musta pissed in my cornflakes this morning. )
