Are you suggesting traffic isn't less than it was, say, 5 years ago?
If you quickly load OT from long ago, it is very clear there were a lot more posts/threads per day than there are now. That is fact.
Which is not what I claimed at all. What I claimed was that traffic slowed before the split and there was no clear difference between traffic in the months before and after the split. What I contested was the implication that traffic slowed due to the split; even if it had any impact on traffic it certainly wasn't the main reason for the decline.
