I share your concerns David, but there's not a lot we can do, if people want to contribute, they will. As you rightly say, why join if you
have nothing to add? Myself, I can always find something to add, or find a subject to post, just to keep a bit of conversation flowing.
There might be the rub, conversation, a lot of people find engaging in conversation daunting, a challenge, me, I find keeping stumm a
challenge in itself, the lads I worked with loved the "crack", being able to recount a funny tale used to keep them amused and then someone else chimes in with one of their own, it is a skill we seem to be losing sadly. I have no doubt there are lots of funny tales out there, lots of wisdom too, but they don't seem to want to share it with us.
