How has it improved

nightline:
Now i could be a bit slow or missed the point but what has anything to do with what people have posted on this post got to do with the this post
My understanding is reply posts have to be about the original post
I could be wrong

To a degree maybe but just like irl discussions debates or gum flapping sessions they can and invariably do stray a little off topic, there is no hard and fast rule that posts on this forum must remain 100% on topic. It should have some connection to the organic flow of the conversation though, to suddenly start talking randomly about KFC hot wings during the middle of a discussion about a WTD regulation queries post would most definitely not be acceptable, like most things in life it all boils down to common sense.
