You have made a very valid request TM.. Undoubtedly, when a soap is running, the current story lines, the current leads and the current happenings should be in more focus...
But as already pointed out in the thread itself, not much people seem to be interested to do that... Of course I have seen the threads being opened; the threads which iniitially seem to be opened for the purpose you have highlighted. But when the thread doesn't move in a desired speed or gain momentum, then the fandom of " the characters or actors whose track have already ended" are provoked or instigated...
And INTIMIDATION??? Seriously???? This is an open democratic Forum. ANYONE can post or make threads for their favourites and discuss about them... You cannot hold those who are active for the passiveness or nonchalance to discuss the present generation and their story... Surely neither are the active ones going to pounce on those who discuss the current generation ( of course as long as it doesn't instigate them) nor is there the thread limitations such that the active ones are not letting others to have the desired number of thread quota...
And no this is not a classroom. The passive ones come face to face with the active ones in the classroom. Hence they might feel intimidated. But this being the virtual Forum, the members don't come face to face with each other, hence there is no question of intimidation...
Threads remain on the first or the second page depending upon the quantum of discussion happening on them and not because the members having their thoughts in the threads on second or even third pages are intimidated by those having discussions in the threads at the first page...
As it is a public Forum one cannot say that a certain thread should remain at the first page or should be relegated into the second one... Just my thoughts, not a debate again...
