@vivify saidHi,
The average GF thread lasts roughly 2 and a half pages before descending into vitriol.
My prediction: this thread won't see a third page before a cockfight breaks out.
since the thread has no obviosu topic besides going off topic I rate the proposition as self-fulfilling prophecy.
If you would want to make an investigation into this you should post (or agree with some others to post) about 10 threads with menaingful topics and see how and if when the veer off.
Some threads in the past were on topic for their whole lifetime. And some living ones are doing pretty well
