Similar thread from a few months ago:
There are only so many darkroom topics. As forum members age they forget they have discussed them before, so they discuss them again. As newcomers come into the hobby, they encounter the problems for the first time, and they discuss them with other newcomers. Old forum members jump in to share their wisdom. The newcomers complain they are being lectured to and leave the forum. The old forum members become indignant and retrench, eventually forgetting they have discussed the topic. The cycle continues.
Meanwhile, with people accidentally stepping on their footswitches so frequently, they are wearing out prematurely with no source off replacement. Does this signal the end of film photography as we know it? The only hope is that an enterprising fellow will invent a footswitch that you can place on your enlarging table and activate with your hand. It is questionable whether he can successfully fund it on Kickstarter. So many old folks have become bitter about their footswitches. That, and nobody can find replacement bulbs for their enlargers. One old forum member suggests using fireflies like in the good old days. Bedlam ensues.
Apropos of old forum members, did you know that a female curmudgeon is referred to as an old trout? Except, of course, in the Urban Dictionary, where every word has a sexual connotation.
