Seems to me that every skill holds it's own language...something that is unique to that skill. As a nurse, when speaking to a Dr or another nurse, I use the language of nursing or medicine. When I learned to skydive, I used that language, too.
As a baby, we learn language, and don't always use it right (I remember saying a bad word and getting in trouble - I didn't know what it meant, either. LOL).
Language, and the special language that goes with a skill, is something that allows people to communicate within a particular group. And while yes, I agree that some folks go overboard with it (I've never seen the digging shows), to me, it's about learning; learning the language of a skill, and learning to communicate with it.
It also shows some enthusiasm...which I think is great in most things (enthusiasm over meth, not so much. LOL). Learning the language of 'digging' (in itself, digging means to make a hole, not necessarily involving metal detecting) is expected, and necessary...otherwise, how could someone even read the boards?
I do get your point, though...just think that a little leeway to the newbies (like me) while we're trying to learn the difference between bling and ice, nector sector and a honey hole, and other various things along with learning how to use a machine to tell us what's under our feet...well, I can't find fault with folks who show enthusiasm.
This all comes from a newbie, so be gentle with me. I've found a total of 6 pennies, so I've got a LONG way to go.
Have a great day!
