The quality of threads is a matter of personal opinion.
People are always referring to the 'Good old days', as if things were better back then.
It's like beauty being in the eye of the beholder, some topics will be of interest to most, but most topics will only be of interest to some.
I have never been concerned with the quality of threads, each to their own, but the hijacking of threads with personal comments that would be better off in the Chat Room(is there a clue in the title
), can be quite annoying.
