It does seem like the detecting forums have been slower compared to when I first joined up, which was only 4 years ago. Although even I do a lot more browsing than posting these days.
The place that seems to get the most posts for detecting is over on reddit. But that place is just more well known to the general public
Never have done the FB-probably never will either.
I would loose the $$$ if I had to give an answer on "What is a reddit?"
The finds on the Banner are only a small snippet of what the membership believe should be awarded the header space. (Well that's to be taken with a grain of salt)
Popularity of the forums is just there's only so many folks in the hobby to go around-and only so much time.
Many probably grab a hunt here and there-and never post up the finds-because of the time it takes isn't there.
Personally if the hobby died tomorrow well

so be it-less folks digging in the dirt raises the odds of my dirt digging being successful.
Was digging in the dirt 35+ years before any of this was happening-the only contact to the outside world was a couple of monthly magazines at the corner store where it was purchased and gleamed over till the pages and stories were worn by all in the household. Now that's another thing that has died-the written stories on a shiny piece of paper, bound by 2 staples.
Many on this forum probably never held one of those magazines-no, if it's not on the device in the paw it just never existed it seems.
There's just an example of a part of this 5 decade long detecting history has gone, lost, except for those that wrote, got published, and for those that read those articles-thanks to you all if your still out there.
Go back 55 yrs ago, and that's what dreams were made of reading about the adventures-gee even the first copy of Oak Island was a story to be told-now it's a click bait piece of sorrow.............
