From my perspective I usually look at most postings, and respond if I see fit.
Some I don't respond to because I either have no interest, or just don't want to comment.
Simple choice really if you don't like a particular thread, ignore it.
I think this board is pretty good most of the time, and like any other board if you don't like it, you know what to do.
I like Geoff's comment about a couple of old boys sharing memories, I would also add putting the world to rights and generally having a good old moan.
I'll be sticking around here all the while board is active.
