It's not a problem on a thread like this where no specific question has been asked by an individual member.The reality is that on threads one thing leads to another. Is that really a problem
It can become a problem when someone asks a specific question and a long winded off topic debate ensues, full of pseudo technical theory and conjecture which swamps the OP and has been known to put members off posting and ultimately off using this forum.
