I also really have to question the necessity of a full six months between last post and Classics induction.
This is necessary so that the immediate excitement surrounding the thread can die down, allowing it to be more objectively evaluated on "yes, this is a worthy and timeless thread" versus "no, although this was a cool thread at the time, it is nothing special six months later".
One way to tell if a thread is a classic is by whether people are still referencing it, or posts covered in it,
in a non-"this must be in the classics" manner, months later.
People went to the trouble of creating some random "classics" section and then nobody bothered to keep up with it. Like I said, it's been years since anything went into it, and if you tell me no thread of note has happened in the last two+ years, I'm highly unlikely to believe you.
There are number of worthy threads in the Classics section. The fact that there haven't been any new ones in two years has no bearing on that. And there's no policy that says we
must continue to add threads to the Classics. Keep in mind that every thread we add, no matter how worthy, will dilute the value of every thread in that section.
EDIT: And actually, I
have added threads to that section in the past year, just not threads that were
posted in the last year. I added the woutersmits and "****ing Batman" threads.
