Isn't that what all social media is?
A place with people of common interest to discuss things.
Yes, the average person who treasure hunts and metal detects is male, over age 35, with a keen interest in history.
I for one am not interested in which baby diaper is the best, which you might find on a parenting social network. Or who the newest comic book character is in a Marvel comic book forum.
I know people who can name every actress and actor, who they are married to and how many children and divorces they have had. That's their interest not mine. But if they want to talk about it with others, good, they found something in life that interest them.
Me, personally, I like the history, the adventure, the research, the challenge.
